+.SS "Repository format conversion"
+The
+.B convert5to6
+subcommand converts a repository of format 5 to format 6.
+It is somewhat dangerous!
+It modifies the repository in place,
+so you should be careful.
+You should do a hardlink copy of the repository before converting:
+.IP
+cp -al repo repo.format5
+.PP
+You should also run this with local filesystem access to the repository,
+rather than sftp,
+to avoid abysmal performance.
