# The config file looks like this. You can have paths to individual
# repos, collections of repos in a directory tree, or both.
#
# [paths]
# virtual/path = /real/path
# virtual/path = /real/path
#
# [collections]
# /prefix/to/strip/off = /root/of/tree/full/of/repos
#
# collections example: say directory tree /foo contains repos /foo/bar,
# /foo/quux/baz. Give this config section:
# [collections]
# /foo = /foo
# Then repos will list as bar and quux/baz.
# Alternatively you can pass a list of ('virtual/path', '/real/path') tuples
# or use a dictionary with entries like 'virtual/path': '/real/path'
