-The Perl, Python, Ruby flavors are like brothers and sisters and the PHP3
-module is like a very close cousin to them.  The Java, Perl, Python, Ruby,
-and Tcl modules are generated using SWIG (http://www.swig.org) while the
-PHP3/PHP4 module is developed using the PHP C API without using SWIG.
+The SWIGMapScript modules are generated by `SWIG <http://www.swig.org>`_. 
+The PHPMapScript module is developed using the PHP C API without using SWIG. 
+PHP users therefore have a choice of using the SWIG generated module or the 
+custom written PHP module.
