v0.028: Revision 0.028

Version 0.028 is largely a bugfix release.  The version number now
includes the git commit ID, using this as the "patch" number.  I have
made it easier for derivative developers to change the name of the
program.

Cheat modes have been added which can be activated from the command
line.

The wording of the special exceptions to the normal Apache License 2.0
has been updated to make the exceptions stronger and aid in their
intended effect.
