# BikeControl — indoor cycling trainer control (Tauri + Svelte + Rust).
#
# Tauri's bundler has no pacman target, so this PKGBUILD builds a real
# .pkg.tar.zst with makepkg. It builds from the *local working tree* (pointed at
# by $BIKECONTROL_SRC), which is what scripts/build-arch.sh sets up. For AUR
# distribution, replace this with a source=() release tarball / VCS URL.

pkgname=bikecontrol
# scripts/build-arch.sh exports BIKECONTROL_PKGVER, derived from git: the tag on
# master/main, the branch name on a feature branch. The fallback below only
# applies when makepkg is run by hand outside that script.
