-=head1 NAME
-
-B<python_distutils> - Python Distutils (setup.py)
-
-=head1 SYNOPSIS
-
-B<dh_auto_*> [B<--buildsystem>=I<python_distutils>] ...
-
-=head1 DESCRIPTION
-
-Python Distribution Utilities (Distutils for short) is a standard Python build
-system. It is used to package most of the Python modules in the source
-distribution form. Typically, only two steps (build and install) are needed to
-finish installation of the Distutils based Python module. This build system can
-be typically identified by presence of the F<setup.py> in the source directory.
-
-=head1 DH_AUTO NOTES
-
-Out of source tree building is done by default but in source building is also
-supported. PLEASE NOTE that B<default build directory> is B<$srcdir/build>
-where $srcdir is a path to the source directory.
-
-Due to design flaws of Distutils, it is not possible to set a B<custom> build
-directory via command line arguments to F<setup.py>. Therefore, the same effect
-is achieved by writing appropriate F<.pydistutils.cfg> file to the build
-directory and pointing $HOME environment variable to the build directory.
