# This file provides simple access to CVS repositories, so that packages
# can be created from CVS instead of from released tarballs.
#
# A package using this file shall define the following variables:
#
#	CVS_REPOSITORIES
#		A list of unique identifiers /id/ for which appropriate
#		CVS_ROOT and CVS_MODULE must be defined.
#
#	CVS_ROOT.${id}
#		The CVSROOT for the CVS repository, including anoncvs
#		password, if applicable.
#
#	CVS_MODULE.${id}
#		The CVS module to check out.
#
# It may define the following variables:
#
#	CVS_TAG
#		The CVS tag to check out (default: HEAD).
#
#	CVS_TAG.${id}
#		Overridable CVS tag for a repository.
#
# This file defines the following variables:
#
#	CVS_ROOT_GNU
#	CVS_ROOT_NONGNU
#	CVS_ROOT_SOURCEFORGE
#		Common CVS repository locations for use in the CVS_ROOT
#		variables.
