[PATCH 1/2] new ANSI escape sequences tapset
- From: Eugene Teo <eteo at redhat dot com>

- Subject: [PATCH 1/2] new ANSI escape sequences tapset
- Reply-to: Eugene Teo <eteo at redhat dot com>
This adds a new tapset for ANSI escape sequences. It is based on an
existing tapset that was written by Masami Hiramatsu for the stapgames
project. This also adds a modified version of the ansi_color.stp script
so that it displays other attributes other than the bold effect.
