The project provides a bootstrapped tarball.  We avoid the “/archive”
URLs on Github as they may change over time.

When using the bootstrapped tarball most of these inputs are not needed.

I have changed both synopsis and description.  We don’t usually mention
UNIX, nor do we repeat the license or the inputs in the description.

You missed the import of (gnu packages wxwidgets), which makes me think
that you haven’t tried building this patch.

I have pushed this to the master branch with commit 7c0411879b after
including my changes.

Thanks!
