-One of the features of Python that makes it so powerful is the ability
-to take existing libraries, written in C or C++, and make them
-available as Python extension modules. Such extension modules are
-often called bindings for the library.
-
-SIP is a tool that makes it very easy to create Python bindings for C
-and C++ libraries. It was originally developed to create PyQt, the
-Python bindings for the Qt toolkit, but can be used to create bindings
-for any C or C++ library.
-
-NOTE:
-This package will, by default, overwrite some files contained in the 
-stock kdebindings package included in Slackware.  The version of sip
-included with kdebindings is an older version which works fine for
-generating qt3/kde3 python bindings, but the newer versions are needed 
-to generate qt4 python bindings (pyqt4 on SlackBuilds.org).  To the
-best of our knowledge, sip is backwards compatible, so there shouldn't
-be any adverse effects from the overwritten files, but we cannot make
-any promises.  If you do encounter problems, remove this sip package
-and reinstall the stock kdebinding package, and then notify the 
-maintainer of this build script (see the sip.info file).
-As an alternative, this build script provides a PREFIX variable that
-can be set to select a different installation prefix (such as /opt).
-Doing so will require you to add the directory in which the sip binary
-is located to your PATH, add the sip includes directory to your 
-compiler includes search path, and add the sip python module path to 
-your PYTHONPATH environment variable.  All of these things will have
-to be done manually and in such a way that they take priority over the
-files installed in /usr prefix.

-# HOW TO EDIT THIS FILE:
-# The "handy ruler" below makes it easier to edit a package description.  Line
-# up the first '|' above the ':' following the base package name, and the '|'
-# on the right side marks the last column you can put a character in.  You must
-# make exactly 11 lines for the formatting to be correct.  It's also
-# customary to leave one space after the ':'.
