 # 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. This or CVSROOT must be set to include ports and documentation.
 #  CVSROOT:    CVS root to obtain the ports and documentation trees. This or
 #   CVSUP_HOST must be set to include ports and documentation.
 #  CVS_TAG:    CVS tag for ports and documentation (HEAD by default)
 #  SVNROOT:    SVN URL to FreeBSD source repository (by default, 
 #   svn://svn.freebsd.org/base)
 #  MAKE_FLAGS: optional flags to pass to make (e.g. -j)
 # 
 #  Note: Since this requires a chroot, release cross-builds will not work!
 #
 # $FreeBSD$
