/*
 *  ======== rel.js ========
 *  This command performs all release data gathering and validation
 *  for a package.
 *
 *  Generate package/package.rel.xml files, check that the declared import
 *  requirements are consistent with the actual versions imported via
 *  the package path, and check that all import requirements are
 *  (recursively) consistent.
 *
 *  usage: rel.js [-f] package-base-dir [output-file]
 *
 *  Options:
 *      -f      (force) consistency checks to not fail; check failures are
 *               always displayed, but the creation of the release normally
 *               fails if compatibility failures are detected.
 *
 *      -v      verbose mode; display information during processing
