# Build script to build BarnOwl for the locker.

# Usage: locker-build [-n] [-o OUTPUT-TGZ] VERSION SOURCE-TARBALL
# -n is a dry-run, and drops to a shell in the build directory
# -o does the install into a temporary directory and tars it into the
#    specified tarball instead.
# SOURCE-TARBALL is a source tarball, created by do-release
# VERSION should be of the form 'barnowl-VERSION'
#
# TODO: Scrape $VERSION from the tarball
