Builtin rules reference
#######################################
*pyke.builtins* module provides a ton of useful functions that will help you to easily write pyke build
files.

In this chapter you will find a description about the basic concepts and a complete reference for
all builtin methods available.

.. note::
  Remember that because pyke uses an internal scheduler that runs and parallelizes jobs, there is a clear difference between pyke functions and pyke rules. Functions are executed when the build file is being processed whereas rules expand jobs that will be processed at a later time, if pyke's internal scheduler decides something needs to be rebuilt.
