 # `tek_engine`
 
-this crate provides the `Engine` trait,
-which defines an application's lifecycle.
-
-currently, there is one kind of engine implemented, `Tui`.
-it uses `ratatui` to present an interactive user interface
-in text mode.
-
-at launch, the `Tui` engine spawns two threads,
-a **render thread** and an **input thread**. (the
-application may spawn further threads, such as a
-**jack thread**.)
-
-all threads communicate using shared ownership,
-`Arc<RwLock>` and `Arc<Atomic>`. the engine and
-application instances are expected to be wrapped
-in `Arc<RwLock>`; internally, those synchronization
-mechanisms may be used liberally.
-
 ## rendering
 
-the **render thread** continually invokes the
-`Content::render` method of the application
-to redraw the display. it does this efficiently
-by using ratatui's double buffering.
-
-thus, for a type to be a valid application for engine `E`,
-it must implement the trait `Content<E>`, which allows
-it to display content to the engine's output.
-
-the most important thing about the `Content` trait is that
-it composes:
-* you can implement `Content::content` to build
-  `Content`s out of other `Content`s
-* and/or `Content::area` for custom positioning and sizing,
-* and/or `Content::render` for custom rendering
-  within the given `Content`'s area.
-
-the manner of output is determined by the
-`Engine::Output` type, a mutable pointer to which
-is passed to the render method, e.g. in the case of
-the `Tui` engine: `fn render(&self, output: &mut TuiOut)`
-
-you can use `TuiOut::blit` and `TuiOut::place`
-to draw at specified coordinates of the display, and/or
-directly modify the underlying `ratatui::Buffer` at
-`output.buffer`
-
-rendering is intended to work with read-only access
-to the application state. if you really need to update
-values during rendering, use interior mutability.
-
 ## input handling
 
 the **input thread** polls for keyboard events

-this codebase produces the following binaries:
+```
+Usage: tek [OPTIONS] <COMMAND>
 
-* **`tek_sequencer`** is a single-track, multi-pattern MIDI sequencer with properly tempo-synced pattern switch
-* **`tek_groovebox`** connects the sequencer to a sampler, so that you can sample while you sequence
-* **`tek_arranger`** is a multi-track sequencer based on a familiar clip launching UI
-* **`tek_transport`** is a JACK transport controller
-* **`tek_sampler`** is a MIDI-controlled sampler
-* **`tek_plugin`** is an audio plugin host.
-* **`tek_channel`** is a standalone channel strip
-* **`tek_mixer`** is an audio mixer.
+Commands:
+  clock      A standalone transport view
+  sequencer  A MIDI sequencer
+  sampler    A MIDI-controlled audio sampler
+  groovebox  Sequencer and sampler together
+  arranger   Multi-track MIDI sequencer
+  mixer      TODO: A MIDI-controlled audio mixer
+  track      TODO: A customizable channel strip
+  plugin     TODO: An audio plugin host
+  help       Print this message or the help of the given subcommand(s)
 
-some of these are currently work in progress.
+Options:
+  -t, --name <NAME>  Name of JACK client
+  -S, --sync-lead    Whether to attempt to become transport master
+  -s, --sync-follow  Whether to sync to external transport master
+  -b, --bpm <BPM>    Initial tempo in beats per minute
+  -h, --help         Print help
+  -V, --version      Print version

-## getting started
+* [x] `arrows/wasd`: navigate
+* [x] `tab`: toggle editor
+* [x] `enter`: write note
+* [x] `z`: unlock zoom
+* [x] `-` / `=`: zoom midi editor
+* [x] space: play/pause
+* [ ] esc: options
+* [ ] f1: help/command list
+* [ ] f2: rename
+* [ ] f6: save
+* [ ] f9: load
+
+## installation
 
 * **requirements:** linux; jack or pipewire; 24-bit terminal (i use `kitty`)
 * **recommended:** midi controller; samples in wav format; lv2 plugins.

-# `tek_edn`
+# `ket`
 
-parser and bindings for tek's configuration language,
-which is based on edn.
+**ket** is the configuration language of **tek**.
+it's based on [edn](https://en.wikipedia.org/wiki/Clojure#Extensible_Data_Notation)
+but without all the features.
+
+## usage
+
+### with `tek_output`
+
+this is a `tek_output` view layout defined using ket:
+
+```edn
+(bsp/s (fixed/y 2 :toolbar)
+  (fill/x (align/c (bsp/w :pool
+    (bsp/s :outputs (bsp/s :inputs (bsp/s :tracks :scenes)))))))
+```
+
+### with `tek_input`
+
+this is a `tek_input` keymap defined using ket:
+
+```edn
+(@u       undo 1)
+(@shift-u redo 1)
+(@e       editor show :pool-clip)
+(@ctrl-a  scene add)
+(@ctrl-t  track add)
+(@tab     pool toggle)
+```
+
+## tokens
+
+ket has 5 "types":
+
+* nil
+* numeric literal
+* symbol
+* key
+* group
+
+### nil
+
+this does nothing.
+
+### numeric literal
+
+numbers are passed through as is. only non-negative integers are supported.
+
+```edn
+0
+123456
+```
+
+### keys
+
+keys are the names of available operations. they look like this:
+
+```edn
+simple-key
+multi-part/key
+```
+
+keys are implemented by the underlying subsystem:
+
+* in `tek_output`, keys are names of layout primitives
+* in `tek_input`, keys are names of commands
+
+### symbols
+
+symbols that start with `:` represent the names of variables
+provided by the `EdnProvide` trait - such as command parameters,
+or entire layout components:
+
+```edn
+:symbol-name
+```
+
+symbols that start with `@` represent keybindings.
+they are parsed in `tek_tui` and look like this:
+
+```edn
+@ctrl-alt-shift-space
+```
+
+### groups
+
+groups represent things like expressions or configuration statements,
+and look like this:
+
+```edn
+(some-key :symbol (some/other-key @another-symbol 123) 456)
+```
+
+## goals
+
+* [ ] const parse
+* [ ] live reload
+* [ ] serialize modified code back to original indentation

+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## 0.4.0
+
+### Changed
+
+- Added deprecation notice.
+
+## 0.3.0
+
+### Fixed
+
+- `SysExEvent` no longer contains invalid data on 64-bit systems ([#170](https://github.com/RustAudio/vst-rs/pull/171)]
+- Function pointers in `AEffect` marked as `extern` ([#141](https://github.com/RustAudio/vst-rs/pull/141))
+- Key character fixes ([#152](https://github.com/RustAudio/vst-rs/pull/152))
+- Doc and deploy actions fixes ([9eb1bef](https://github.com/RustAudio/vst-rs/commit/9eb1bef1826db1581b4162081de05c1090935afb))
+- Various doc fixes ([#177](https://github.com/RustAudio/vst-rs/pull/177))
+
+### Added
+
+- `begin_edit` and `end_edit` now in `Host` trait ([#151](https://github.com/RustAudio/vst-rs/pull/151))
+- Added a `prelude` for commonly used items when constructing a `Plugin` ([#161](https://github.com/RustAudio/vst-rs/pull/161))
+- Various useful implementations for `AtomicFloat` ([#150](https://github.com/RustAudio/vst-rs/pull/150))
+
+### Changed
+
+- **Major breaking change:** New `Plugin` `Send` requirement ([#140](https://github.com/RustAudio/vst-rs/pull/140))
+- No longer require `Plugin` to implement `Default` ([#154](https://github.com/RustAudio/vst-rs/pull/154))
+- `impl_clicke` replaced with `num_enum` ([#168](https://github.com/RustAudio/vst-rs/pull/168))
+- Reworked `SendEventBuffer` to make it useable in `Plugin::process_events` ([#160](https://github.com/RustAudio/vst-rs/pull/160))
+- Updated dependencies and removed development dependency on `time` ([#179](https://github.com/RustAudio/vst-rs/pull/179))
+
+## 0.2.1
+
+### Fixed

+- Introduced zero-valued `EventType` variant to enable zero-initialization of `Event`, fixing a panic on Rust 1.48 and newer ([#138](https://github.com/RustAudio/vst-rs/pull/138))
+- `EditorGetRect` opcode returns `1` on success, ensuring that the provided dimensions are applied by the host ([#115](https://github.com/RustAudio/vst-rs/pull/115))
+
+### Added
+
+- Added `update_display()` method to `Host`, telling the host to update its display (after a parameter change) via the `UpdateDisplay` opcode ([#126](https://github.com/RustAudio/vst-rs/pull/126))
+- Allow plug-in to return a custom value in `can_do()` via the `Supported::Custom` enum variant ([#130](https://github.com/RustAudio/vst-rs/pull/130))
+- Added `PartialEq` and `Eq` for `Supported` ([#135](https://github.com/RustAudio/vst-rs/pull/135))
+- Implemented `get_editor()` and `Editor` interface for `PluginInstance` to enable editor support on the host side ([#136](https://github.com/RustAudio/vst-rs/pull/136))
+- Default value (`0.0`) for `AtomicFloat` ([#139](https://github.com/RustAudio/vst-rs/pull/139))
+
+## 0.2.0
+
+### Changed
+
+- **Major breaking change:** Restructured `Plugin` API to make it thread safe ([#65](https://github.com/RustAudio/vst-rs/pull/65))
+- Fixed a number of unsoundness issues in the `Outputs` API ([#67](https://github.com/RustAudio/vst-rs/pull/67), [#108](https://github.com/RustAudio/vst-rs/pull/108))
+- Set parameters to be automatable by default ([#99](https://github.com/RustAudio/vst-rs/pull/99))
+- Moved repository to the [RustAudio](https://github.com/RustAudio) organization and renamed it to `vst-rs` ([#90](https://github.com/RustAudio/vst-rs/pull/90), [#94](https://github.com/RustAudio/vst-rs/pull/94))
+
+### Fixed
+
+- Fixed a use-after-move bug in the event iterator ([#93](https://github.com/RustAudio/vst-rs/pull/93), [#111](https://github.com/RustAudio/vst-rs/pull/111))
+
+### Added
+
+- Handle `Opcode::GetEffectName` to resolve name display issues on some hosts ([#89](https://github.com/RustAudio/vst-rs/pull/89))
+- More examples ([#65](https://github.com/RustAudio/vst-rs/pull/65), [#92](https://github.com/RustAudio/vst-rs/pull/92))
+
+## 0.1.0
+
+### Added
+
+- Added initial changelog
+- Initial project files
+
+### Removed
+
+- The `#[derive(Copy, Clone)]` attribute from `Outputs`.
+
+### Changed
+- The signature of the `Outputs::split_at_mut` now takes an `self` parameter instead of `&mut self`.
+So calling `split_at_mut` will now move instead of "borrow".
+- Now `&mut Outputs` (instead of `Outputs`) implements the `IntoIterator` trait.
+- The return type of the `AudioBuffer::zip()` method (but it still implements the Iterator trait).

+[![Discord Chat][discord-img]][discord-url]
+[![Discourse topics][dc-img]][dc-url]
+
+> **Notice**: `vst-rs` is deprecated.
+>
+> This crate is no longer actively developed or maintained. VST 2 has been [officially discontinued](http://web.archive.org/web/20210727141622/https://www.steinberg.net/en/newsandevents/news/newsdetail/article/vst-2-coming-to-an-end-4727.html) and it is [no longer possible](https://forum.juce.com/t/steinberg-closing-down-vst2-for-good/27722/25) to acquire a license to distribute VST 2 products. It is highly recommended that you make use of other libraries for developing audio plugins and plugin hosts in Rust.
+>
+> If you're looking for a high-level, multi-format framework for developing plugins in Rust, consider using [NIH-plug](https://github.com/robbert-vdh/nih-plug/) or [`baseplug`](https://github.com/wrl/baseplug/). If you're looking for bindings to specific plugin APIs, consider using [`vst3-sys`](https://github.com/RustAudio/vst3-sys/), [`clap-sys`](https://github.com/glowcoil/clap-sys), [`lv2(-sys)`](https://github.com/RustAudio/rust-lv2), or [`auv2-sys`](https://github.com/glowcoil/auv2-sys). If, despite the above warnings, you still have a need to use the VST 2 API from Rust, consider using [`vst2-sys`](https://github.com/RustAudio/vst2-sys) or generating bindings from the original VST 2 SDK using [`bindgen`](https://github.com/rust-lang/rust-bindgen).
+
+`vst-rs` is a library for creating VST2 plugins in the Rust programming language.
+
+This library is a work in progress, and as such it does not yet implement all
+functionality. It can create basic VST plugins without an editor interface.
+
+**Note:** If you are upgrading from a version prior to 0.2.0, you will need to update
+your plugin code to be compatible with the new, thread-safe plugin API. See the
+[`transfer_and_smooth`](examples/transfer_and_smooth.rs) example for a guide on how
+to port your plugin.
+
+## Library Documentation
+
+Documentation for **released** versions can be found [here](https://docs.rs/vst/).
+
+Development documentation (current `master` branch) can be found [here](https://rustaudio.github.io/vst-rs/vst/).
+
+## Crate
+This crate is available on [crates.io](https://crates.io/crates/vst).  If you prefer the bleeding-edge, you can also
+include the crate directly from the official [Github repository](https://github.com/rustaudio/vst-rs).
+
+```toml
+# get from crates.io.
+vst = "0.3"
+```
+```toml
+# get directly from Github.  This might be unstable!
+vst = { git = "https://github.com/rustaudio/vst-rs" }
+```
+
+## Usage
+To create a plugin, simply create a type which implements the `Plugin` trait. Then call the `plugin_main` macro, which will export the necessary functions and handle dealing with the rest of the API.
+
+## Example Plugin
+A simple plugin that bears no functionality. The provided `Cargo.toml` has a
+`crate-type` directive which builds a dynamic library, usable by any VST host.
+
+`src/lib.rs`
+
+```rust
+#[macro_use]
+extern crate vst;
+
+use vst::prelude::*;
+
+struct BasicPlugin;
+
+impl Plugin for BasicPlugin {
+    fn new(_host: HostCallback) -> Self {
+        BasicPlugin
+    }
+
+    fn get_info(&self) -> Info {
+        Info {
+            name: "Basic Plugin".to_string(),
+            unique_id: 1357, // Used by hosts to differentiate between plugins.
+            ..Default::default()
+        }
+    }
+}
+
+plugin_main!(BasicPlugin); // Important!
+```
+
+`Cargo.toml`
+
+```toml
+[package]
+name = "basic_vst"
+version = "0.0.1"
+authors = ["Author <author@example.com>"]
+
+[dependencies]
+vst = { git = "https://github.com/rustaudio/vst-rs" }
+
+[lib]
+name = "basicvst"
+crate-type = ["cdylib"]
+```

+
+#### Packaging on OS X
+
+On OS X VST plugins are packaged inside loadable bundles.
+To package your VST as a loadable bundle you may use the `osx_vst_bundler.sh` script this library provides. 
+
+Example: 
+
+```
+./osx_vst_bundler.sh Plugin target/release/plugin.dylib
+Creates a Plugin.vst bundle
+```

+//! since we can't easily solve a nonlinear equation,

+#![warn(missing_docs)]
+
+//! A rust implementation of the VST2.4 API.
+//!
+//! The VST API is multi-threaded. A VST host calls into a plugin generally from two threads -
+//! the *processing* thread and the *UI* thread. The organization of this crate reflects this
+//! structure to ensure that the threading assumptions of Safe Rust are fulfilled and data
+//! races are avoided.
+//!
+//! # Plugins
+//! All Plugins must implement the `Plugin` trait and `std::default::Default`.
+//! The `plugin_main!` macro must also be called in order to export the necessary functions
+//! for the plugin to function.
+//!
+//! ## `Plugin` Trait
+//! All methods in this trait have a default implementation except for the `get_info` method which
+//! must be implemented by the plugin. Any of the default implementations may be overridden for
+//! custom functionality; the defaults do nothing on their own.
+//!
+//! ## `PluginParameters` Trait
+//! The methods in this trait handle access to plugin parameters. Since the host may call these
+//! methods concurrently with audio processing, it needs to be separate from the main `Plugin`
+//! trait.
+//!
+//! To support parameters, a plugin must provide an implementation of the `PluginParameters`
+//! trait, wrap it in an `Arc` (so it can be accessed from both threads) and
+//! return a reference to it from the `get_parameter_object` method in the `Plugin`.
+//!
+//! ## `plugin_main!` macro
+//! `plugin_main!` will export the necessary functions to create a proper VST plugin. This must be
+//! called with your VST plugin struct name in order for the vst to work.
+//!
+//! ## Example plugin
+//! A barebones VST plugin:
+//!
+//! ```no_run
+//! #[macro_use]
+//! extern crate vst;
+//!
+//! use vst::plugin::{HostCallback, Info, Plugin};
+//!
+//! struct BasicPlugin;
+//!
+//! impl Plugin for BasicPlugin {
+//!     fn new(_host: HostCallback) -> Self {
+//!         BasicPlugin
+//!     }
+//!
+//!     fn get_info(&self) -> Info {
+//!         Info {
+//!             name: "Basic Plugin".to_string(),
+//!             unique_id: 1357, // Used by hosts to differentiate between plugins.
+//!
+//!             ..Default::default()
+//!         }
+//!     }
+//! }
+//!
+//! plugin_main!(BasicPlugin); // Important!
+//! # fn main() {} // For `extern crate vst`
+//! ```
+//!
+//! # Hosts
+//!
+//! ## `Host` Trait
+//! All hosts must implement the [`Host` trait](host/trait.Host.html). To load a VST plugin, you
+//! need to wrap your host in an `Arc<Mutex<T>>` wrapper for thread safety reasons. Along with the
+//! plugin path, this can be passed to the [`PluginLoader::load`] method to create a plugin loader
+//! which can spawn plugin instances.
+//!
+//! ## Example Host
+//! ```no_run
+//! extern crate vst;
+//!
+//! use std::sync::{Arc, Mutex};
+//! use std::path::Path;
+//!
+//! use vst::host::{Host, PluginLoader};
+//! use vst::plugin::Plugin;
+//!
+//! struct SampleHost;
+//!
+//! impl Host for SampleHost {
+//!     fn automate(&self, index: i32, value: f32) {
+//!         println!("Parameter {} had its value changed to {}", index, value);
+//!     }
+//! }
+//!
+//! fn main() {
+//!     let host = Arc::new(Mutex::new(SampleHost));
+//!     let path = Path::new("/path/to/vst");
+//!
+//!     let mut loader = PluginLoader::load(path, host.clone()).unwrap();
+//!     let mut instance = loader.instance().unwrap();
+//!
+//!     println!("Loaded {}", instance.get_info().name);
+//!
+//!     instance.init();
+//!     println!("Initialized instance!");
+//!
+//!     println!("Closing instance...");
+//!     // Not necessary as the instance is shut down when it goes out of scope anyway.
+//!     // drop(instance);
+//! }
+//!
+//! ```
+//!

-# `ket`
-
-**ket** is the configuration language of **tek**.
-it's based on [edn](https://en.wikipedia.org/wiki/Clojure#Extensible_Data_Notation)
-but without all the features.
-
-## usage
-
-### with `tek_output`
-
-this is a `tek_output` view layout defined using ket:
-
-```edn
-(bsp/s (fixed/y 2 :toolbar)
-  (fill/x (align/c (bsp/w :pool
-    (bsp/s :outputs (bsp/s :inputs (bsp/s :tracks :scenes)))))))
-```
-
-### with `tek_input`
-
-this is a `tek_input` keymap defined using ket:
-
-```edn
-(@u       undo 1)
-(@shift-u redo 1)
-(@e       editor show :pool-clip)
-(@ctrl-a  scene add)
-(@ctrl-t  track add)
-(@tab     pool toggle)
-```
-
-## tokens
-
-ket has 4 "types", represented by variants of the `Value` enum:
-
-* `Num` - numeric literal
-* `Sym` - textual symbol
-* `Key` - textual key
-* `Exp` - parenthesized group of tokens
-
-### numeric literal
-
-numbers are passed through as is. only non-negative integers are supported.
-
-```edn
-0
-123456
-```
-
-### keys
-
-keys are the names of available operations. they look like this:
-
-```edn
-simple-key
-multi-part/key
-```
-
-keys are implemented by the underlying subsystem:
-
-* in `tek_output`, keys are names of layout primitives
-* in `tek_input`, keys are names of commands
-
-### symbols
-
-symbols that start with `:` represent the names of variables
-provided by the `Context` trait - such as command parameters,
-or entire layout components:
-
-```edn
-:symbol-name
-```
-
-symbols that start with `@` represent keybindings.
-they are parsed in `tek_tui` and look like this:
-
-```edn
-@ctrl-alt-shift-space
-```
-
-### parenthesized groups
-
-parenthesized groups represent things like expressions
-or configuration statements, and look like this:
-
-```edn
-(some-key :symbol (some/other-key @another-symbol 123) 456)
-```
-
-## goals
-
-* [ ] const parse
-* [ ] live reload
-* [ ] serialize modified code back to original indentation

-# `tek_output`
-
-## free floating layout primitives
-
-this crate exposes several layout operators
-which work entirely in unsigned coordinates
-and are generic over `tek_engine::Engine`
-and `tek_engine::Content`. chiefly, they
-are not dependent on rendering framework.
-
-|operator|description|
-|-|-|
-|**`When(x, a)`**|render `a` only when `x == true`|
-|**`Either(x, a, b)`**|render `a` when `x == true`, otherwise render `b`|
-|**`Map(get_iterator, callback)`**|transform items in uniform way|
-|**`Bsp`**|concatenative layout|
-|...|...|
-|**`Align`**|pin content along axis|
-|...|...|
-|**`Fill`**|**make content's dimension equal to container's:**|
-|`Fill::x(a)`|use container's width for content|
-|`Fill::y(a)`|use container's height for content|
-|`Fill::xy(a)`|use container's width and height for content|
-|**`Fixed`**|**assign fixed dimension to content:**|
-|`Fixed::x(w, a)`|use width `w` for content|
-|`Fixed::y(w, a)`|use height `w` for content|
-|`Fixed::xy(w, h, a)`|use width `w` and height `h` for content|
-|**`Expand`/`Shrink`**|**change dimension of content:**|
-|`Expand::x(n, a)`/`Shrink::x(n, a)`|increment/decrement width of content area by `n`|
-|`Expand::y(n, a)`/`Shrink::y(n, a)`|increment/decrement height of content area by `m`|
-|`Expand::xy(n, m, a)`/`Shrink::xy(n, m, a)`|increment/decrement width of content area by `n`, height by `m`|
-|**`Min`/`Max`**|**constrain dimension of content:**|
-|`Min::x(w, a)`/`Max::x(w, a)`|enforce minimum/maximum width `w` for content|
-|`Min::y(h, a)`/`Max::y(h, a)`|enforce minimum/maximum height `h` for content|
-|`Min::xy(w, h, a)`/`Max::xy(w, h, a)`|enforce minimum/maximum width `w` and height `h` for content|
-|**`Push`/`Pull`**|**move content along axis:**|
-|`Push::x(n, a)`/`Pull::x(n, a)`|increment/decrement `x` of content area|
-|`Push::y(n, a)`/`Pull::y(n, a)`|increment/decrement `y` of content area|
-|`Push::xy(n, m, a)`/`Pull::xy(n, m, a)`|increment/decrement `x` and `y` of content area|
-
-**todo:**
-* sensible `Margin`/`Padding`
-* `Reduce`
-
-## example rendering loop
-
-the **render thread** continually invokes the
-`Content::render` method of the application
-to redraw the display. it does this efficiently
-by using ratatui's double buffering.
-
-thus, for a type to be a valid application for engine `E`,
-it must implement the trait `Content<E>`, which allows
-it to display content to the engine's output.
-
-the most important thing about the `Content` trait is that
-it composes:
-* you can implement `Content::content` to build
-  `Content`s out of other `Content`s
-* and/or `Content::area` for custom positioning and sizing,
-* and/or `Content::render` for custom rendering
-  within the given `Content`'s area.
-
-the manner of output is determined by the
-`Engine::Output` type, a mutable pointer to which
-is passed to the render method, e.g. in the case of
-the `Tui` engine: `fn render(&self, output: &mut TuiOut)`
-
-you can use `TuiOut::blit` and `TuiOut::place`
-to draw at specified coordinates of the display, and/or
-directly modify the underlying `ratatui::Buffer` at
-`output.buffer`
-
-rendering is intended to work with read-only access
-to the application state. if you really need to update
-values during rendering, use interior mutability.

-# `tek_tui`
-
-the `Tui` struct (the *engine*) implements the
-`tek_input::Input` and `tek_output::Output` traits.
-
-at launch, the `Tui` engine spawns two threads,
-a **render thread** and an **input thread**. (the
-application may spawn further threads, such as a
-**jack thread**.)
-
-all threads communicate using shared ownership,
-`Arc<RwLock>` and `Arc<Atomic>`. the engine and
-application instances are expected to be wrapped
-in `Arc<RwLock>`; internally, those synchronization
-mechanisms may be used liberally.

+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>

+you'll need a Rust toolchain and various system libraries.
+
+you can obtain the former using `rustup` and the latter using `nix-shell`.
+there's a `shell.nix` provided with the project.
+
+from there, use the commands in the `Justfile`, e.g.:
+
+```sh
+just arranger
+```
+
+note that `tek > 0.2.0-rc.7` will require rust nightly
+for the unstable features `type_alias_impl_trait` and
+`impl_trait_in_assoc_type`. make some noise for lucky
+[**rust rfc2515**](https://github.com/rust-lang/rust/issues/63063)
+if you want to see this buildable with stable/beta.

+This directory contains Dockerfiles and shell scripts
+for building Tek in a container. For now, only the
+GLIBC build works, as the Musl static build is unable
+to `dlopen` the system's `libjack.so`.
+
+Invoke from repo root, like this: `build/release-glibc.sh`.
+This will first build a Docker image, `tek:glibc`, which
+will contain all build-time dependencies; then, it
+will invoke a `cargo build --release` in a container
+spawned from that image, ultimately placing the
+release build in this directory, as `build/tek`.

Subject: [PATCH 649/652] almost compiles

that has subsided for now. somewhat.

going to amend this commit with fixes to

and then... what?
