Usage: $PROG [options] <cfgfile.ini>

This script is useful for debugging the configuration file, and configuration
parsing engine. It will print out the environment variables created by running
parse_config and parse_prj_config for each project.

<cfgfile.ini>      - the configuration file.

Options:
  -v, --verbose    be verbose;
  -w, --workdir    working directory to store temporary files (defaults to /tmp)
  -h, --help       show this text and exit.
