@Mooon Both easyblocks are not small, so maybe it would help to have separate PRs for them, to easy to review/testing process.
Unless there's a reason they're bundled together?

perhaps inherit from the MakeCp generic easyblock to avoid reimplementing some of its functionality?

@boegel I did an single PR for both easyblocks because the two softwares are linked together: up to date the Stitch library is developed for use with the SPPARKS software. But I can also separate them into two PRs if it makes it easier to review/testing

@Mooon No need for two separate PRs, but looking into the suggested changes would be nice.
