# build-calamares-modules.sh: builds Calamares' packagechooserq module (the
# QML page the Steamify page runs in) for the ISO. CachyOS's
# cachyos-calamares-next leaves it out of its own build, so it's built here,
# out of tree, from CachyOS's Calamares source against the installed
# cachyos-calamares-next, and installed into airootfs. Run as root in the
# build container, before buildiso.sh: the package comes from the same repos
# at the same time as the ISO's, so the module matches the ISO's Calamares.
# Records the version it was built for next to it (calamares-online.sh
# compares that with the Calamares it ends up with).
