#
# Distribution generator for CVS based packages.
# To work, this script needs a consistent tagging of all releases.
# Each release of a package should have a tag of the form
#
#  <package>_<version>
#
# where <package> is the package name and the CVS module
# and <version> s the version number with underscores instead of dots.
#
# For example: cvs tag php_3_0a1
#
# The distribution ends up in a .tar.gz file that contains the distribution
# in a directory called <package>-<version>.  The distribution contains all
# directories from the CVS module except the one called "nodist", but only
# the files INSTALL, README and config* are included.
#
# Since you can no longer set the CVS password via an env variable, you
# need to have previously done a cvs login for the server and user id
# this script uses so it will have an entry in your ~/.cvspasswd file.
#
# Usage: makedist <package> <version>
