-Sphinx is a tool that makes it easy to create intelligent and beautiful
-documentation for Python projects (or other documents consisting of multiple
-reStructuredText sources), written by Georg Brandl.  It was originally created
-for the new Python documentation, and has excellent facilities for Python
-project documentation, but C/C++ is supported as well, and more languages are
-planned.
+**Sphinx makes it easy to create intelligent and beautiful documentation.**
 
 Sphinx uses reStructuredText as its markup language, and many of its strengths
 come from the power and straightforwardness of reStructuredText and its parsing
 and translating suite, the Docutils.
 
-Among its features are the following:
