1.4 +"""Append module search paths for third-party packages to sys.path.
1.5 +
1.6 +****************************************************************
1.7 +* This module is automatically imported during initialization. *
1.8 +****************************************************************
1.9 +
1.10 +In earlier versions of Python (up to 1.5a3), scripts or modules that
1.11 +needed to use site-specific modules would place ``import site''
1.12 +somewhere near the top of their code. Because of the automatic
1.13 +import, this is no longer necessary (but code that does it still
1.14 +works).
1.15 +
1.16 +This will append site-specific paths to the module search path. On
1.17 +Unix, it starts with sys.prefix and sys.exec_prefix (if different) and
1.18 +appends lib/python<version>/site-packages as well as lib/site-python.
1.19 +It also supports the Debian convention of
1.20 +lib/python<version>/dist-packages. On other platforms (mainly Mac and
1.21 +Windows), it uses just sys.prefix (and sys.exec_prefix, if different,
1.22 +but this is unlikely). The resulting directories, if they exist, are
1.23 +appended to sys.path, and also inspected for path configuration files.
1.24 +
1.25 +FOR DEBIAN, this sys.path is augmented with directories in /usr/local.
1.26 +Local addons go into /usr/local/lib/python<version>/site-packages
1.27 +(resp. /usr/local/lib/site-python), Debian addons install into
1.28 +/usr/{lib,share}/python<version>/dist-packages.
1.29 +
1.30 +A path configuration file is a file whose name has the form
1.31 +<package>.pth; its contents are additional directories (one per line)
1.32 +to be added to sys.path. Non-existing directories (or
1.33 +non-directories) are never added to sys.path; no directory is added to
1.34 +sys.path more than once. Blank lines and lines beginning with
1.35 +'#' are skipped. Lines starting with 'import' are executed.
1.36 +
1.37 +For example, suppose sys.prefix and sys.exec_prefix are set to
1.38 +/usr/local and there is a directory /usr/local/lib/python2.X/site-packages
1.39 +with three subdirectories, foo, bar and spam, and two path
1.40 +configuration files, foo.pth and bar.pth. Assume foo.pth contains the
1.41 +following:
1.42 +
1.43 + # foo package configuration
1.44 + foo
1.45 + bar
1.46 + bletch
1.47 +
1.48 +and bar.pth contains:
1.49 +
1.50 + # bar package configuration
1.51 + bar
1.52 +
1.53 +Then the following directories are added to sys.path, in this order:
1.54 +
1.55 + /usr/local/lib/python2.X/site-packages/bar
1.56 + /usr/local/lib/python2.X/site-packages/foo
1.57 +
1.58 +Note that bletch is omitted because it doesn't exist; bar precedes foo
1.59 +because bar.pth comes alphabetically before foo.pth; and spam is
1.60 +omitted because it is not mentioned in either path configuration file.
1.61 +
1.62 +After these path manipulations, an attempt is made to import a module
1.63 +named sitecustomize, which can perform arbitrary additional
1.64 +site-specific customizations. If this import fails with an
1.65 +ImportError exception, it is silently ignored.
