Patch pushed as 1afffdaa63d34a810943aa5a6b8cc03d42cc3bd2 with the
following modifications:
 - copyright line for you added
 - 'commit' and 'revision' declared at the top of the package definition
 - use of the 'git-version' function to define the version
 - '#:asd-files' argument removed as it is not necessary in this case
   (all the asd files are read by default)
 - "fiveam" added to native-inputs as it is required by the
   "markup.test" system
 - inputs sorted
 - synopsis shortened a little
 - commit message fixed (you wrote "fonts.scm" instead of "lisp-xyz.scm")

Thanks.
