+'''
+This script attempts to extract what options have been added since the
+specified revision (usually a tag, but any revision that git recognizes may be
+provided). It accepts an optional second revision to use as the cut-off. The
+default is your LOCAL "master". Thus, you should ensure that this is up to date
+before running this script.
+
+This script works by extracting the set of options before and after every
+commit that affected ':src/options.h' and computing the differences. It should,
+therefore, be fairly robust (for example, options that moved around won't show
+up). However, if an option is removed and subsequently re-added, or if an
+option was added and subsequently removed, the resulting records will need to
+be reconciled manually.
