+"""
+A simple tool to integrate protocol buffers into your build system.
+
+Example::
+
+    def configure(conf):
+        conf.load('compiler_cxx cxx protoc')
+
+    def build(bld):
+        bld(
+                features = 'cxx cxxprogram'
+                source   = 'main.cpp file1.proto proto/file2.proto', 
+                include  = '. proto',
+                target   = 'executable') 
+
+Notes when using this tool:
+
+- protoc command line parsing is tricky.
+
+  The generated files can be put in subfolders which depend on
+  the order of the include paths.
+
+  Try to be simple when creating task generators
+  containing protoc stuff.
