# Source Generated with Decompyle++ # File: in.pyc (Python 2.2) """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 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. 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. 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/python1.5/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/python1.5/site-packages/bar /usr/local/lib/python1.5/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.
