"""Wrapper for mod_fcgid, for use as a CherryPy HTTP server when testing. To autostart fcgid, the "apache" executable or script must be on your system path, or you must override the global APACHE_PATH. On some platforms, "apache" may be called "apachectl", "apache2ctl", or "httpd"--create a symlink to them if needed. You'll also need the WSGIServer from flup.servers. See http://projects.amor.org/misc/wiki/ModPythonGateway KNOWN BUGS ========== 1. Apache processes Range headers automatically; CherryPy's truncated output is then truncated again by Apache. See test_core.testRanges. This was worked around in http://www.cherrypy.org/changeset/1319. 2. Apache does not allow custom HTTP methods like CONNECT as per the spec. See test_core.testHTTPMethods. 3. Max request header and body settings do not work with Apache. 4. Apache replaces status "reason phrases" automatically. For example, CherryPy may set "304 Not modified" but Apache will write out "304 Not Modified" (capital "M"). 5. Apache does not allow custom error codes as per the spec. 6. Apache (or perhaps modpython, or modpython_gateway) unquotes %xx in the Request-URI too early. 7. mod_python will not read request bodies which use the "chunked" transfer-coding (it passes REQUEST_CHUNKED_ERROR to ap_setup_client_block instead of REQUEST_CHUNKED_DECHUNK, see Apache2's http_protocol.c and mod_python's requestobject.c). 8. Apache will output a "Content-Length: 0" response header even if there's no response entity body. This isn't really a bug; it just differs from the CherryPy default.

The abstract syntax itself might change with each Python release; this module helps to find out programmatically what the current grammar looks like and allows modifications of it. An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as a flag to the `compile()` builtin function or by using the `parse()` function from this module. The result will be a tree of objects whose classes all inherit from `ast.AST`. A modified abstract syntax tree can be compiled into a Python code object using the built-in `compile()` function. Additionally various helper functions are provided that make working with the trees simpler. The main intention of the helper functions and this module in general is to provide an easy to use interface for libraries that work tightly with the python syntax (template engines for example). :copyright: Copyright 2008 by Armin Ronacher. :license: Python License.

The `escape` function returns markup objects so that double escaping can't happen. The constructor of the :class:`Markup` class can be used for three different things: When passed an unicode object it's assumed to be safe, when passed an object with an HTML representation (has an `__html__` method) that representation is used, otherwise the object passed is converted into a unicode string and then assumed to be safe: >>> Markup("Hello <em>World</em>!")
