Great, thank you! I'll point upstream to it. And I guess it is another weak point that upstream didn't autotoolize it, but uses a custom Makefile.

But on another Sage list it was stated by someone that the package was experimental, which caused some trouble. And thus I got the impression that I should ask here first.

One more thing: I added proper error handling. MeatAxe upstream sources do provide hooks for callback functions, but error return values are not correctly propagated. That's fixed by one of my patches, too, so that the inversion of a singular matrix doesn't just crash but results in a ZeroDivision error.

The MeatAxe executables cfcomp checksum chop decomp genmod mkcycl mkdotl mkgraph mkhom mkhom_old mkinc mksub mktree orbrep precond pseudochop pwkond rad soc symnew tcond tuc zad zbl zcf zcl zcp zct zcv zef zev zfr ziv zkd zmo zmu zmw znu zor zpo zpr zpt zqt zro zsc zsi zsp zsy ztc zte ztr zts zuk zvp as well as the upstream library libmtx.a are built and installed. So, technically, all functionality is exposed. But more Cython wrappers are needed to use it from within Sage.
