+# Based on upwork-appimage package on the AUR

+# There's no central repository for AppImages, and no convention on
+# system-wide AppImage installations, so we're picking /opt/appimages.
+# We grab koreader.png and koreader.desktop from the AppImage, patch the koreader.desktop,
+# and install them as we would other apps, for convenience sake.
