If you have another suggestion don't hesitate to email it to me. It also helps me if you report on the status of your pre-release experiences, good and bad. This helps determine the readiness of the pre-release to become a full release. GPM is not in the CVS archive, for that either download the real gpm and patch it, or download the current release or development version of imwheel and compile it in there. You can configure gpm and avoid imwheel if you like when you use the imwheel archives to get it.
Instructions mkdir a directory to check the files out into, and cd into it.
A short note on distributions including imwheel. Most distributions remove my version of gpm from the imwheel package. I do not support the regular gpm, nor do I support anything in the current incarnation of gpm I have, except for the wheel functionality and the extra mice.
