+swig - Simplified Wrapper and Interface Generator
+
+[synopsis]
+swig [ options ] " file"
+
+[description]
+The swig command is used to create wrapper code to connect C and C++ code to
+scripting languages like Perl, Python, Tcl etc. from the definition of the
+interface. For detailed information on writing those interface definitions
+please refer to /usr/share/doc/swig-doc/Doc/Manual/index.html from the swig-doc
+package.
+
+This manpage concentrates on explaining the invocation of the swig command.

+%description
+SWIG is a compiler that attempts to make it easy to integrate C, C++,
+or Objective-C code with scripting languages including Perl, Tcl, and
+Python.In a nutshell, you give it a bunch of ANSI C/C++ declarations and
+it generates an interface between C and your favorite scripting language.
+However, this is only scratching the surface of what SWIG can do--some
+of its more advanced features include automatic documentation generation,
+module and library management, extensive customization options, and more.
