Editing Advanced Installation (section)

===Python API===
This API requires [http://www.swig.org/ SWIG], [http://numpy.scipy.org/ numpy] and the Python development kit. Numpy requires Python 2.4 or newer (i.e. RHEL 5 or newer). However, these dependencies are unnecessary for the common case when Python is just used as [http://en.wikipedia.org/wiki/Glue_language glue] to create chains of programs, and it only needs to read the RSF header, and not the binary. To allow Python [http://en.wikipedia.org/wiki/Meta-programs metaprograms] in madagascar to function, and programming in this style to be done, a fallback development kit implementing only the header-related functionality will be installed in the lack of these dependencies.
