+"""Support for Sphinx documentation
+
+This is a wrapper for sphinx-build program. Please note that sphinx-build supports only one output format which can
+passed to build via sphinx_output_format attribute. The default output format is html.
+
+Example wscript:
+
+def configure(cnf):
+    conf.load('sphinx')
+
+def build(bld):
+    bld(
+        features='sphinx',
+        sphinx_source='sources',  # path to source directory
+        sphinx_options='-a -v',  # sphinx-build program additional options
+        sphinx_output_format='man'  # output format of sphinx documentation
+        )
