#!/bin/sh

# generate-release.sh: check out source trees, and build release components with
#  totally clean, fresh trees.
#
#  Usage: generate-release.sh [-r revision] [-d docrevision] \
#	[-p portsrevision] svn-branch scratch-dir
#
# Environment variables:
#  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)
#  RELSTRING:  optional base name for media images (e.g. FreeBSD-9.0-RC2-amd64)
# 
#  Note: Since this requires a chroot, release cross-builds will not work!
#
# $FreeBSD$
