# generate-release.sh: check out source trees, and build release components with
#  totally clean, fresh trees.
#
#  Usage: generate-release.sh svn-branch scratch-dir
#
# Environment variables:
#  CVSUP_HOST: Host of a cvsup server to obtain the ports and documentation
#   trees. Must be set to include ports and documentation.
#  CVSUP_TAG:  CVS tag for ports and documentation (HEAD by default)
#  MAKE_FLAGS: optional flags to pass to make (e.g. -j)
# 
#  Note: Since this requires a chroot, release cross-builds will not work!
