short_description: Gentoo Image Builder for Cloud and Turnkey ISO installers
version_added: "1.0.0"
description:
* This project enables easy access to building ``systemd`` or ``openrc`` -based images.
* Performs automatic download AND verification of the linux iso, stage3 tarball and portage.
* Caches the iso and stage3 .txt files for at most a day before redownloading and rechecking for new files
* Sane and readable cli commands to build, run and test.
* Step system to enable user to continue off at the same place if a step fails
* No heavy packages like rust included ** TODO
