Subject: build.sh: Add [--help] {build|missing} support
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=3cce8b79a317b5b71da55a8af46c7ba00e9d9538;p=dockerfile.git

build.sh: Add [--help] {build|missing} support

The 'missing' command show which repos remain unbuilt.  I use this to
setup the REPOS environtment variable for subsequent build calls, if
on of the repos is giving me trouble.
