+SUMMARY = """
+Python is an interpreted, interactive, object-oriented programming
+language. It is often compared to Tcl, Perl, Scheme or Java.
+
+Python combines remarkable power with very clear syntax. It has
+modules, classes, exceptions, very high level dynamic data types, and
+dynamic typing. There are interfaces to many system calls and
+libraries, as well as to various windowing systems (X11, Motif, Tk,
+Mac, MFC). New built-in modules are easily written in C or C++. Python
+is also usable as an extension language for applications that need a
+programmable interface.
+
+The Python implementation is portable: it runs on many brands of UNIX,
+on Windows, DOS, OS/2, Mac, Amiga... If your favorite system isn't
+listed here, it may still be supported, if there's a C compiler for
+it. Ask around on comp.lang.python -- or just try compiling Python
+yourself.
