+     "SWIG is an interface compiler that connects programs written in C and
+C++ with languages such as Perl, Python, Ruby, Scheme, and Tcl.  It works by
+taking the declarations found in C/C++ header files and using them to generate
+the wrapper code that scripting languages need to access the underlying C/C++
+code.  In addition, SWIG provides a variety of customization features that let
+you tailor the wrapping process to suit your application.")
