+=head1 FORK NOTES
+
+This is a fork of the Verilator project which adds some steps for automatically
+creating .deb and .rpm packages from a release tag. Travis is configured to
+run a build and upload a release to GitHub whenever a tag is created. You can
+simply cherry-pick the latest commit on top of a real Verilator release and
+create a tag from that.
