If a package (spkg) is installed while the environment variable SAGE_CHECK=yes
is set, then the test suite of the spkg is run. This is what *should* be
the case. Note, however, that not all spkg have a test suite.

Also, it is possible to create a Debug version --- by which we found a
couple of memory corruptions in (lib)Singular that have not been noticed
upstream before. I don't recall what environment variable needs to be
set, though. SAGE_DEBUG=yes, perhaps. Or DEBUG=yes.

By the way, I do feel the need to know more about software engineering.
Learning by doing sometimes is not good enough.

Best regards,
Simon
