Using "#:tests? #f" is much shorter and does the same thing as the
build phase modification you put above. See the "gnushogi" package
definition in gnu/packages/games.scm for an example.

Squirrel's license looks like the Expat license to me. The Zlib license
has a numbered list of restrictions, which Squirrel's does not.

Also, when adding a new file to the gnu/packages directory, the file
must be added to the GNU_SYSTEM_MODULES list of files in gnu/local.mk.

I've tested your submitted patch with all the changes I mentioned above, but
I am not sure whether or not there is an existing module we may place
this package in instead of creating a new one. I'll get back to you ASAP
on that.

Otherwise, thank you again for this patch, and I look forward to seeing
it as part of Guix! :)
