Tutorials and Introduction
==========================
* `To-Do Tutorial <http://pythonpaste.org/todo/TodoTutorial.html>`_
The core Paste package is a set of tools that use `WSGI
<http://www.python.org/peps/pep-0333.html>`_ heavily as the means of
communication. WSGI is an in-process CGI-like communication protocol.
Right now the best way to see the various tools available in Paste is
to `look through the source <module-index.html>`_.

Overview
========
If you don't want to look through source, here's a quick overview of
what there is here:
Testing
-------
* A fixture for testing WSGI applications conveniently and in-process,
in ``paste.fixture``
* A fixture for testing command-line applications, also in
``paste.fixture``
* Check components for WSGI-compliance in ``paste.lint``
Dispatching
-----------
* Chain and cascade WSGI applications (returning the first non-error
response) in ``paste.cascade``
* Dispatch to several WSGI applications based on URL prefixes, in
``paste.urlmap``
* Allow applications to make subrequests and forward requests
internally, in ``paste.recursive``
Web Application
---------------
* Run CGI programs as WSGI applications in ``paste.cgiapp`` (and
Python-sepcific CGI programs with ``paste.pycgiwrapper``)
* Traverse files and load WSGI applications from ``.py`` files (or
static files), in ``paste.urlparser``
* Serve static directories of files, also in ``paste.urlparser``
Tools
-----
* Catch HTTP-related exceptions (e.g., ``HTTPNotFound``) and turn them
into proper responses in ``paste.httpexceptions``
* Check for signed cookies for authentication, setting ``REMOTE_USER``
in ``paste.login``
* Create sessions in ``paste.session`` and ``paste.flup_session``
* Gzip responses in ``paste.gzip``
* A wide variety of routines for manipulating WSGI requests and
producing responses, in ``paste.wsgilib``
Debugging Filters
-----------------
* Catch (optionally email) errors with extended tracebacks (using
Zope/ZPT conventions) in ``paste.exceptions``
* Catch errors presenting a `cgitb
<http://python.org/doc/current/lib/module-cgitb.html>`_-based
output, in ``paste.cgitb_catcher``.
* Profile each request and append profiling information to the HTML,
in ``paste.profilemiddleware``
* Capture ``print`` output and present it in the browser for
debugging, in ``paste.printdebug``
* Validate all HTML output from applications using the `WDG Validator
<http://www.htmlhelp.com/tools/validator/>`_, appending any errors
or warnings to the page, in ``paste.wdg_validator``
Other Tools
-----------
* A file monitor to allow restarting the server when files have been
updated (for automatic restarting when editing code) in
``paste.reloader``
* A class for generating and traversing URLs, and creating associated
HTML code, in ``paste.url``
