+# 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.
