This is just a quick message following up on the new API documentation pages (http://www.nmr-relax.com/api/1.2/). I have added a target to the Scons script to compile the API documentation (in both the 1.2 and 1.3 repository lines). This requires the installation of both Epydoc (using the svn repository sources by typing 'svn co https://svn.sourceforge.net/svnroot/epydoc/trunk/epydoc', going into the 'src' directory, then typing 'python setup.py install' as root) and the Graphviz software. The HTML pages will be placed in the directory 'docs/api'. To create the API documentation, within the relax base directory type: $ scons api_manual_html Then look at 'docs/api/index.html'. Edward
