# sharpemu-bin - SharpEmu (https://github.com/sharpemu/sharpemu), an
# experimental PlayStation 5 emulator written in C#.
#
# Upstream publishes prebuilt linux-x64 release assets itself, so there is no
# build_artifact() here: on a new version only pkgver and the checksums are
# refreshed and the result is pushed to the AUR.
#
# Upstream versions contain hyphens (v0.0.2-beta.4), which an Arch pkgver
# must not; latest_version therefore reports the underscored form
# (0.0.2_beta.4) and the PKGBUILD derives the upstream form back via _upver.
