which.py dev build script
Usage:
python build.py [<options>...] [<targets>...]
Options:
--help, -h Print this help and exit.
--targets, -t List all available targets.
This is the primary build script for the which.py project. It exists
to assist in building, maintaining, and distributing this project.
It is intended to have Makefile semantics. I.e. 'python build.py'
will build execute the default target, 'python build.py foo' will
build target foo, etc. However, there is no intelligent target
interdependency tracking (I suppose I could do that with function
attributes).
