"""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
|
8 |
needed to use site-specific modules would place ``import site''
|
9 |
somewhere near the top of their code. Because of the automatic
|
10 |
import, this is no longer necessary (but code that does it still
|
11 |
works).
|
12 |
|
13 |
This will append site-specific paths to the module search path. On
|
14 |
Unix, it starts with sys.prefix and sys.exec_prefix (if different) and
|
15 |
appends lib/python<version>/site-packages as well as lib/site-python.
|
16 |
It also supports the Debian convention of
|
17 |
lib/python<version>/dist-packages. On other platforms (mainly Mac and
|
18 |
Windows), it uses just sys.prefix (and sys.exec_prefix, if different,
|
19 |
but this is unlikely). The resulting directories, if they exist, are
|
20 |
appended to sys.path, and also inspected for path configuration files.
|
21 |
|
22 |
FOR DEBIAN, this sys.path is augmented with directories in /usr/local.
|
23 |
Local addons go into /usr/local/lib/python<version>/site-packages
|
24 |
(resp. /usr/local/lib/site-python), Debian addons install into
|
25 |
/usr/{lib,share}/python<version>/dist-packages.
|
26 |
|
27 |
A path configuration file is a file whose name has the form
|
28 |
<package>.pth; its contents are additional directories (one per line)
|
29 |
to be added to sys.path. Non-existing directories (or
|
30 |
non-directories) are never added to sys.path; no directory is added to
|
31 |
sys.path more than once. Blank lines and lines beginning with
|
32 |
'#' are skipped. Lines starting with 'import' are executed.
|
33 |
|
34 |
For example, suppose sys.prefix and sys.exec_prefix are set to
|
35 |
/usr/local and there is a directory /usr/local/lib/python2.X/site-packages
|
36 |
with three subdirectories, foo, bar and spam, and two path
|
37 |
configuration files, foo.pth and bar.pth. Assume foo.pth contains the
|
38 |
following:
|
39 |
|
40 |
# foo package configuration
|
41 |
foo
|
42 |
bar
|
43 |
bletch
|
44 |
|
45 |
and bar.pth contains:
|
46 |
|
47 |
# bar package configuration
|
48 |
bar
|
49 |
|
50 |
Then the following directories are added to sys.path, in this order:
|
51 |
|
52 |
/usr/local/lib/python2.X/site-packages/bar
|
53 |
/usr/local/lib/python2.X/site-packages/foo
|
54 |
|
55 |
Note that bletch is omitted because it doesn't exist; bar precedes foo
|
56 |
because bar.pth comes alphabetically before foo.pth; and spam is
|
57 |
omitted because it is not mentioned in either path configuration file.
|
58 |
|
59 |
After these path manipulations, an attempt is made to import a module
|
60 |
named sitecustomize, which can perform arbitrary additional
|
61 |
site-specific customizations. If this import fails with an
|
62 |
ImportError exception, it is silently ignored.
