Usage: $( basename $0 ) [-n] [-t] [-p] arg [arg ...]

Options:
  -t  Don't track filesystem writes (passed to sbrun).
  -n  Allow network access (passed to sbrun).
  -p  If a binary package already exists for a given build, install
      it instead of building a new one.

Run this script from the top level of a SBo repo clone!

If arg is a file, its contents are added to the list of builds. Use -
to read a list of builds from stdin (possibly piped from sbodeps -q).

If arg is a directory, it's added to the list.

If arg is neither, it's assumed to be a bare build name (with no category/
directory) and searched for.

Full sbopkg queue syntax is NOT supported, only a simple list of builds
(no |VAR=value, no @file, no -app). If you need sbopkg, use sbopkg!

Once the list is built, each build is downloaded with sbodl, built with
sbrun -c, and installed with upkg, in the order given.

The -p option requires SlackBuild scripts that support the
PRINT_PACKAGE_NAME option (Slackware 15.0 and up). It searches
for built packages in the same place SlackBuild scripts place them
(OUTPUT, TMP, or /tmp).
