4 Cabal supports specifying different information for various common source
5 control systems. This is the name of the source control system used for a
6 repository. The currently recognised types are:
12 - ``mercurial`` (or alias ``hg``)
13 - ``bazaar`` (or alias ``bzr``)
18 The VCS kind will determine what other fields are appropriate to specify for a
19 particular version control system.
