wscript - Waf build script for Protolib
See http://waf.googlecode.com/ for more information.

In order to use different build directories (for example, a release and a debug
build), use the -o (--out) flag when configuring.  For example:

    ./waf configure -o build-debug --debug
    ./waf

    ./waf configure -o build-release
    ./waf
