"""
This is a WAF build script (http://code.google.com/p/waf/).
It can be used as an alternative build system to autotools
for Geany. It does not (yet) cover all of the autotools tests and
configure options but all important things are working.
"make dist" should be done with autotools, most other targets and
functions should work better (regarding performance and flexibility)
or at least equally.

Missing features: --enable-binreloc, make targets: dist, pdf (in doc/)
Known issues: Dependency handling is buggy, e.g. if src/document.h is
              changed, depending source files are not rebuilt (maybe Waf bug).

The code of this file itself loosely follows PEP 8 with some exceptions
(line width 100 characters and some other minor things).

Requires WAF 1.6.1 and Python 2.5 (or later).
