# A remote repository can be specified on the command line
# in one of the following formats:
#
#	<repo>
#	<repo> <head>
#	<repo> tag <tag>
#
# where <repo> could be one of:
#
#	a URL (including absolute or local pathname)
#	a short-hand
#	a short-hand followed by a trailing path
#
# A short-hand <name> has a corresponding file $GIT_DIR/branches/<name>,
# whose contents is a URL, possibly followed by a URL fragment #<head>
# to name the default branch on the remote side to fetch from.
