-CGI script is the entrypoint that web-server calls when a web-request to an application is made. The `trac.cgi` script can be created using the `trac-admin <env> deploy <dir>` command which automatically substitutes the required paths, see TracInstall#cgi-bin. Make sure the script is executable by your web server.

  1. Use a `ScriptAlias` directive that maps a URL to the `trac.cgi` script (recommended)

+=== Python Egg Cache
+
+The [TracInstall#egg-cache egg-cache] can be configured using an `os.environ` statement in `trac.cgi`, as shown above.
+To do the same from the Apache configuration, use the `SetEnv` directive:
+{{{#!apache
+SetEnv PYTHON_EGG_CACHE /path/to/dir
+}}}

+Put this directive next to where you set the path to the [TracEnvironment Trac environment], i.e. in the same `<Location>` block.

 === Using WSGI
 
-You can run a [http://henry.precheur.org/python/how_to_serve_cgi WSGI handler] [http://pythonweb.org/projects/webmodules/doc/0.5.3/html_multipage/lib/example-webserver-web-wsgi-simple-cgi.html under CGI].  You can [wiki:TracModWSGI#Thetrac.wsgiscript write your own application function], or use the deployed trac.wsgi's application.
