+#
+#    convert-external-repos [OPTIONS...] -s [DIR] -r [HOST]
+#     
+# == Arguments (mandatory)
+#
+#   -s, --scm-dir=DIR         use DIR as base directory for repositories
+#   -r, --redmine-host=HOST   assume Redmine is hosted on HOST. Examples:
+#                             -r redmine.example.net
+#                             -r http://redmine.example.net
+#                             -r https://example.net/redmine
+#   -k, --key=KEY             use KEY as the Redmine API key
+#   -c, --command=COMMAND     use this command to update each external
+#                             repository: command is called with the name
+#                             of the project, the path to its repo, and
+#                             its external repo url as its three args
+#
+# == Options
+#
+#   --http-user=USER          User for HTTP Basic authentication with Redmine WS
+#   --http-pass=PASSWORD      Password for Basic authentication with Redmine WS
+#   -t, --test                only show what should be done
+#   -h, --help                show help and exit
+#   -v, --verbose             verbose
+#   -V, --version             print version and exit
+#   -q, --quiet               no log
