+graph-tool --- an efficient python module for analysis of graphs
+================================================================
 
 graph-tool is an efficient python module for manipulation and
 statistical analysis of graphs. It contains several general graph
 measurements data structures and algorithms, such as degree or
 properties distributions, degree or properties correlations,
-clustering, graph filtering, graph layout, and more, as well as a
-random graph generation routine. For more information and
-documentation, please take a look at the website
-http://graph-tool.skewed.de.
+clustering, graph filtering, interactive graph layout, random graph
+generation, detection of community structure, and more.
+
+Contrary to most other python modules with similar functionality, the
+core data structures and algorithms are implemented in C++, making
+extensive use of template metaprogramming, based heavily on the Boost
+Graph Library. This confers it a level of performance that is
+comparable (both in memory usage and computation time) to that of a
+pure C/C++ library.

 Availability
-============
+------------
 
 The current stable version of graph-tool is always available from the
 project's website: http://graph-tool.skewed.de
 
 Installation
-============
+------------
 
 graph-tool follows the standard GNU installation procedure.  Please
 consult the INSTALL file in this distribution for more detailed
 instructions.
 
-Note that recent versions of GCC (4.4 or above) are required for
-compilation, and due to the usage of template metaprogramming
-techniques in the program, relatively large amounts of RAM are
-required during compilation. You have been warned! For this reason,
-pre-compiled packages are available in the website.
