Nice tool, could have used this back in uni! The packaged examples work
just fine and I was able to quickly play around with particles without
fuzz.
Some things:
${WRKSRC}/TODO mentions known issues including crashes. Maybe you want
to transport this information into your package somehow so users will
know in advance (and won't bother with duplicate reports).
Please sort *_DEPENDS alphabetically.
Saw this during build, not sure if it will lead to picking up things
endusers might not have:
-- The following OPTIONAL packages have been found:
* KF5DocTools
* GSL, GSL, <http://eigen.tuxfamily.org>
Provides a GSL-powered solver for Step
* Qalculate
