Hi Lars,

I came across your patch and took a quick look. You seem to only install
the exprtk.hpp file, but the Github repository has lots of other things. 
Is this what you intended?

Dear Futurile,

yes, copying exprtk.hpp only is intended. It contains the full (header-only) library. The license file is also copied into the store package.

Sincerely,
Lars

Hello Lars,

apologies, the previous version slipped through my attention. I have
just committed the patch with a few changes:
- reordered the fields
- added a "(file-name (git-file-name name version))" line to the source
  field
- Turned the description into a sentence.

Thanks!

Andreas
