+/** This header file includes all the definitions for the

+ ** The reason for functions prototyped with #define's is
+ ** to allow for maximum Python portability. It also uses
+ ** Python as the runtime linker, which allows for late binding.
+ '' For more information on this style of development, read
+ ** the Python docs on this subject.
+ ** http://www.python.org/doc/current/ext/using-cobjects.html
+ **
+ ** If using this to build your own derived extensions,
+ ** you'll see that the functions available here are mainly
+ ** used to help convert between python objects and SDL objects.
+ ** Since this library doesn't add a lot of functionality to
+ ** the SDL library, it doesn't need to offer a lot either.
+ **
+ ** When initializing your extension module, you must manually
+ ** import the modules you want to use. (this is the part about
+ ** using python as the runtime linker). Each module has its
+ ** own import_xxx() routine. You need to perform this import
+ ** after you have initialized your own module, and before
+ ** you call any routines from that module. Since every module
+ ** in pygame does this, there are plenty of examples.

+ ** The base module does include some useful conversion routines

+pip - The Python Package Installer
+==================================

+
+pip is the `package installer`_ for Python. You can use pip to install packages from the `Python Package Index`_ and other indexes.
+
+Please take a look at our documentation for how to install and use pip:
+
+* `Installation`_
+* `Usage`_
+
+We release updates regularly, with a new version every 3 months. Find more details in our documentation:
+
+* `Release notes`_
+* `Release process`_
+
+In pip 20.3, we've `made a big improvement to the heart of pip`_; `learn more`_. We want your input, so `sign up for our user experience research studies`_ to help us do it right.
+
+**Note**: pip 21.0, in January 2021, removed Python 2 support, per pip's `Python 2 support policy`_. Please migrate to Python 3.
+
+If you find bugs, need help, or want to talk to the developers, please use our mailing lists or chat rooms:
+
+* `Issue tracking`_
+* `Discourse channel`_
+* `User IRC`_
+
+If you want to get involved head over to GitHub to get the source code, look at our development documentation and feel free to jump on the developer mailing lists and chat rooms:
+
+* `GitHub page`_
+* `Development documentation`_
+* `Development mailing list`_
+* `Development IRC`_
+
+Code of Conduct
+---------------
