Pytools is a big bag of things that are needed by packages created by Andreas Kloeckner. They are used by python-pycuda and python-pyopencl packages. They contain, amongst other:
* A ton of small tool functions such as len_iterable, argmin, tuple
generation, permutation generation, ASCII table pretty printing,
GvR's mokeypatch_xxx() hack, the elusive flatten, and much more
* A time-series logging module, pytools.log
* Batch job submission, pytools.batchjob
* A lexer, pytools.lex
