ArtCraft Crafting Apps built from the upstream storytold sources.

Targets are openSUSE Tumbleweed, Leap 15.6/15.7/16.0/16.1,
CentOS Stream 10, Fedora 44 and Fedora Rawhide on x86_64; aarch64
is enabled where the target provides a suitable Rust toolchain
(Leap 15.6 is x86_64 only).

The packages carry their own specs and sources. openSUSE uses
cargo-packaging; EL and Fedora use cargo-rpm-macros, with
rust-srpm-macros on Fedora and rust-srpm-macros-epel from EPEL 10
on EL.
