+"""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 (including Mac OSX), it starts with sys.prefix and
+sys.exec_prefix (if different) and appends
+lib/python<version>/site-packages as well as lib/site-python.
+On other platforms (such as Windows), it tries each of the
+prefixes directly, as well as with lib/site-packages appended. The
+resulting directories, if they exist, are appended to sys.path, and
+also inspected for path configuration files.
+
+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/python2.5/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/python2.5/site-packages/bar
+ /usr/local/lib/python2.5/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.
