Comment (by SimonKing):
Meanwhile I have a version of the C-part of the old group cohomology
package that installs fine and even passes a self-test (namely tests that
several of the installed executables work together to build the basic data
for the cohomology computation of the dihedral group of order 8).
However, so far I have no idea how to make it so that the package is only
built if meataxe (from #12103) is installed.
And then of course I have to put all Singular and Gap files with the
appropriate file name extensions into the appropriate folders, and put the
Cython and Python code into the Sage library, as an optional extension.
If I understand correctly, it is needed to add "optional:
modular_resolution" basically to each single line of test (several
hundreds, I guess). Is there really no way to state that a whole file
should only be tested optionally? I believe it is a fairly natural thing
to test an optional extension optionally.
