+Autowaf
+=======
+
+This is autowaf, a bundle of waf and a few extensions intended to be easy to
+use directly as source code in a project.  Using this as a submodule or subtree
+named `waflib` in a project allows waf to be used without including binary
+encoded data in the waf script.  This gets along with revision control and
+distributions better, among other advantages, without losing
+self-containedness.
+
+To use this in a project, add this repository as a directory named `waflib` in
+the top level of the project, and link or copy `waf` to the top level.
+
+Two waf extras are also included: `autowaf.py` and `lv2.py`.
+
+The `autowaf.py` module is a kitchen sink of Python utilities for building
+consistent packages, and can be imported in a wcript as
+`waflib.extras.autowaf`.
+
+The `lv2.py` extra defines options for LV2 plugin installation paths.  It can
+be used by calling `opt.load('lv2')` and `conf.load('lv2')` in the appropriate
+locations in a wscript.
