# schist-bin - Schist (https://github.com/Infrawrench/schist), a layered image
|
|
# editor in Rust (gpui) with PSD and Affinity support.
|
|
#
|
|
# Upstream builds the Linux release itself and publishes a .pkg.tar.zst per
|
|
# architecture, which the PKGBUILD repackages, as upstream's own
|
|
# packaging/linux/aur/schist-bin does. GitHub lists each asset's sha256, so a
|
|
# new version needs no download.
|
|
#
|
|
# The asset name carries upstream's package release
|
|
# (schist-<version>-<release>-<arch>.pkg.tar.zst), which is synced into
|
|
# _relver. The binary needs the same libraries as the source package, so the
|
|
# dependencies are checked against upstream's source PKGBUILD of the same tag:
|
|
# a missing one would not break the test build, only the app.
