Installation
A justfile is included by default for the casey/just command runner.

Translators
Fluent is used for localization of the software. Fluent's translation files are found in the i18n directory. New translations may copy the English (en) localization of the project, rename en to the desired ISO 639-1 language code, and then translations can be provided for each message identifier. If no translation is necessary, the message may be omitted.
Packaging
If packaging for a Linux distribution, vendor dependencies locally with the vendor rule, and build with the vendored sources using the build-vendored rule. When installing files, use the rootdir and prefix variables to change installation paths.
just vendor
just build-vendored
just rootdir=debian/noctua prefix=/usr install
It is recommended to build a source tarball with the vendored dependencies, which can typically be done by running just vendor on the host system before it enters the build environment.
Developers
Developers should install rustup and configure their editor to use rust-analyzer. To improve compilation times, disable LTO in the release profile, install the mold linker, and configure sccache for use with Rust. The mold linker will only improve link times if LTO is disabled.
