-"""Append module search paths for third-party packages to sys.path.
-
-****************************************************************
-* This module is automatically imported during initialization. *
-****************************************************************
-
-In earlier versions of Python (up to 1.5a3), scripts or modules that
-needed to use site-specific modules would place ``import site''
-somewhere near the top of their code.  Because of the automatic
-import, this is no longer necessary (but code that does it still
-works).
-
-This will append site-specific paths to the module search path.  On
-Unix, it starts with sys.prefix and sys.exec_prefix (if different) and
-appends lib/python<version>/site-packages as well as lib/site-python.
-It also supports the Debian convention of
-lib/python<version>/dist-packages.  On other platforms (mainly Mac and
-Windows), it uses just sys.prefix (and sys.exec_prefix, if different,
-but this is unlikely).  The resulting directories, if they exist, are
-appended to sys.path, and also inspected for path configuration files.
-
-FOR DEBIAN, this sys.path is augmented with directories in /usr/local.
-Local addons go into /usr/local/lib/python<version>/site-packages
-(resp. /usr/local/lib/site-python), Debian addons install into
-/usr/{lib,share}/python<version>/dist-packages.
-
-A path configuration file is a file whose name has the form
-<package>.pth; its contents are additional directories (one per line)
-to be added to sys.path.  Non-existing directories (or
-non-directories) are never added to sys.path; no directory is added to
-sys.path more than once.  Blank lines and lines beginning with
-'#' are skipped. Lines starting with 'import' are executed.
-
-For example, suppose sys.prefix and sys.exec_prefix are set to
-/usr/local and there is a directory /usr/local/lib/python2.X/site-packages
-with three subdirectories, foo, bar and spam, and two path
-configuration files, foo.pth and bar.pth.  Assume foo.pth contains the
-following:
-
-  # foo package configuration
-  foo
-  bar
-  bletch
-
-and bar.pth contains:
-
-  # bar package configuration
-  bar
-
-Then the following directories are added to sys.path, in this order:
-
-  /usr/local/lib/python2.X/site-packages/bar
-  /usr/local/lib/python2.X/site-packages/foo
-
-Note that bletch is omitted because it doesn't exist; bar precedes foo
-because bar.pth comes alphabetically before foo.pth; and spam is
-omitted because it is not mentioned in either path configuration file.
-
-After these path manipulations, an attempt is made to import a module
-named sitecustomize, which can perform arbitrary additional
-site-specific customizations.  If this import fails with an
-ImportError exception, it is silently ignored.
