+    This is a hack to use public git repos as F-Droid repos.  It
+    recreates the git repo from scratch each time, so that there is no
+    history.  That keeps the size of the git repo small.  Services
+    like GitHub or GitLab have a size limit of something like 1 gig.
+    This git repo is only a git repo for the purpose of being hosted.
+    For history, there is the archive section, and there is the binary
+    transparency log.
