Hello!

The source of this package contains custom setup.py script, which does
not work with python-build-system, so I just copied files around in
package definition, and this seems worked.

However, I am not sure if it is an appropriate way of intallation.

For cross-compilation and to make "--without-tests" work, this phase
needs to respect #:tests?, try

        (replace 'check
          (lambda* (#:key tests? #:allow-other-keys)
            (when tests?
              (invoke "py.test" "-v")))))))

Most of the time (but not always!), the default build and install
phases and the default of #:use-setuptools? is fine.  Could you
elaborate what is the issue?

Nevermind, I now see the original message you sent.  Still seems
suboptimal though ...

Perhaps the description can be extended a bit? Maybe:

"This package consists of Python modules and scripts for manipulating
stereolithography (STL) files.  It can convert STL files into POV-ray
meshes, PDF and PostScript.  The Python modules allow for reading
and writing STL files.  It supports both the text and binary forms
of STL."

Maxime.

To make sure that 'stl2pov' and friends of 'python-sltools' can find
its dependencies when run outside a profile (somewhat niche but
occassionaly useful), some wrapping may be necessary (search for 'wrap-
program').  Maybe python-build-system does that automatically though
...
