|
# This file provides simple access to CVS repositories, so that packages
|
|
# can be created from CVS instead of from released tarballs. Whenever a
|
|
# package is fetched from CVS, an archive is created from it and saved
|
|
# in ${DISTDIR}/cvs-packages, to save bandwidth.
|
|
#
|
|
# === User-settable variables ===
|
|
#
|
|
# CHECKOUT_DATE
|
|
# Date to check out in ISO format (YYYY-MM-DD).
|
|
#
|
|
# === Package-settable variables ===
|
|
#
|
|
# A package using this file shall define the following variables:
|
|
#
|
|
# CVS_REPOSITORIES
|
|
# A list of unique identifiers. For each of those identifiers, the
|
|
# following variables define the details of how to access the
|
|
# CVS repository.
|
|
#
|
|
# CVS_ROOT.${id}
|
|
# The CVSROOT for the CVS repository, including anoncvs password,
|
|
# if applicable.
|
|
#
|
|
# Examples:
|
|
# ${CVS_ROOT_GNU}/emacs
|
|
# :pserver:anoncvs:@anoncvs.example.com:/cvsroot/project
|
|
#
|
|
# CVS_MODULE.${id}
|
|
# The CVS module to check out.
|
|
#
|
|
# Default value: ${id}
|
|
#
|
|
# It may define the following variables:
|
|
#
|
|
# CVS_TAG.${id}
|
|
# Overridable CVS tag for a repository.
|
|
#
|
|
# Default: ${CVS_TAG} (today at midnight)
|
|
#
|
|
# CVS_TAG
|
|
# The default CVS tag that is checked out. May be overridden by
|
|
# CVS_TAG.${id}.
|
|
#
|
|
# Default value: today at midnight.
|
|
#
|
|
# CVS_PROJECT
|
|
# The project name to be used in CVS_ROOT_SOURCEFORGE.
|
|
#
|
|
# Default: ${PKGBASE}
|
|
#
|
|
# === Variables defined here ===
|
|
#
|
|
# 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.
|
|
#
|
|
# It also provides default values for the following variables, differing
|
|
# from the system-wide defaults:
|
|
#
|
|
# DISTFILES
|
|
# Is set to an empty list, since that is the right choice for most
|
|
# of the CVS packages.
|
|
#
|
|
# PKGNAME
|
|
# Is set to consist of the package name from DISTNAME, combined
|
|
# with the current date. This is useful when no CVS_TAG variables
|
|
# are defined. When they are defined (and there may be multiple
|
|
# ones), the package author should define PKGNAME explicitly.
|
|
#
|
|
# PKGREVISION
|
|
# If PKGREVISION is not set, set it to today's date. This is
|
|
# useful for packages that automatically grab the latest code
|
|
# from CVS every time they are built.
