Usage: %s [options ...] paths ...

-p packageName -- Find and register a package. Looks in the paths for

a sub-directory with the name of the package, and

adds a path entry for the package.

-a appName -- Unconditionally add an application name to the path.

A new path entry is create with the app name, and the

|
paths specified are added to the registry.
|
|
-c -- Add the specified paths to the core Pythonpath.
|
|
If a path appears on the core path, and a package also
|
|
needs that same path, the package will not bother
|
|
registering it. Therefore, By adding paths to the
|
|
core path, you can avoid packages re-registering the same path.
|
|
-m filename -- Find and register the specific file name as a module.
|
|
Do not include a path on the filename!
|
|
--shell -- Register everything with the Win95/NT shell.
|

--upackage name -- Unregister the package

|
--uapp name -- Unregister the app (identical to --upackage)

--umodule name -- Unregister the module

If no options are processed, the program attempts to validate and set

the standard Python path to the point where the standard library is

available. This can be handy if you move Python to a new drive/sub-directory,

in which case most of the options would fail (as they need at least string.py,

Running without options should repair Python well enough to run with
