"""
*Builders* are small executable chunks that together can be linked into a useful build
process. Aside from two helper functions (:func:`stop()` and :func:`info()`)
to fail the build and display an informational message, respectively, all other
functions in this module are builders.
Builders are decorated with ``@tzk_builder``, a synonym for
:func:`_lazy_evaluable()`, which causes them to be lazy-evaluated: that is,
when they're initially called in the configuration, instead of running the
function and returning its result, a zero-argument function with all of the
arguments wrapped up is returned, to be run at a later time. This allows the
configuration file to be read at any time to retrieve information about the
defined products without actually running any build steps.
You can write and use custom builders right within your config file
by decorating them with ``@builders.tzk_builder``.
