+Usage:  gitolite list-dangling-repos
+
+List all existing repos that no one can access remotely any more.  They could
+be normal repos that were taken out of "repo" statements in the conf file, or
+wildcard repos whose matching "wild" pattern was taken out or changed so it no
+longer matches.
+
+I would advise caution if you use this as a basis for deleting repos from the
+file system.  A bug in this program could cause you to lose important data!

+# get the two lists we need.  %repos is the list of repos in "repo" statements
+# in the conf file.  %phy_repos is the list of actual repos on disk.  Our job
+# is to cull %phy_repos of all keys that have a matching key in %repos, where
+# "matching" means "string equal" or "regex match".
