Pytools is a big bag of things that are "missing" from the Python
standard library. This is mainly a dependency of my other software
packages, and is probably of little interest to you unless you use
those. If you're curious nonetheless, here's what's on offer:

* 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.
* Michele Simionato's decorator module.
* A time-series logging module, pytools.log.
* Batch job submission, pytools.batchjob.
* A lexer, pytools.lex.
