## This script builds the panda source tarball.
##
##
## The source tarball contains a hardwired version-number.  You specify
## the version number using the options --v1, --v2, --v3.
##
## The source tarball contains most of what is in CVS, but some of the
## control files (like the CVS directories themselves) are stripped out.
##
## The source tarball contains an rpmbuild 'spec' file so that you can
## easily build a binary RPM: rpmbuild -tb panda3d-version.tar.GZ
##
## The 'spec' file included in the tarball uses the 'makepanda' build
## system to compile panda.
