big bag of things supplementing Python standard library

 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
