 ==== Generating the Trac cgi-bin directory #cgi-bin
 
-In order for Trac to function properly with FastCGI you need to have a `trac.fcgi` file and for mod_wsgi a `trac.wsgi` file. These are Python scripts which load the appropriate Python code. They can be generated using the `deploy` option of [TracAdmin trac-admin].
-
-There is, however, a bit of a chicken-and-egg problem. The [TracAdmin trac-admin] command requires an existing environment to function, but complains if the deploy directory already exists. This is a problem, because environments are often stored in a subdirectory of the deploy. The solution is to do something like this:
-{{{#!sh
-mkdir -p /usr/share/trac/projects/my-project
-trac-admin /usr/share/trac/projects/my-project initenv
-trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
-mv /tmp/deploy/* /usr/share/trac
-}}}
-Don't forget to check that the web server has the execution right on scripts in the `/usr/share/trac/cgi-bin` directory.
+Application scripts for CGI, FastCGI and mod-wsgi can be generated using the [TracAdmin trac-admin] `deploy` command:
+[[TracAdminHelp(deploy)]]
+
+Grant the web server execution right on scripts in the `cgi-bin` directory.
+
+For example, the following yields a typical directory structure:
+{{{#!sh
+$ mkdir -p /var/trac
+$ trac-admin /var/trac/<project> initenv
+$ trac-admin /var/trac/<project> deploy /var/www
+$ ls /var/www
+cgi-bin htdocs
+$ chmod ugo+x /var/www/cgi-bin/*

 ==== Mapping Static Resources
@@ -299 +300 @@
 There are two primary URL paths for static resources: `/chrome/common` and `/chrome/site`. Plugins can add their own resources, usually accessible at the `/chrome/<plugin>` path.
 
-A single `/chrome` alias can used if the static resources are extracted for all plugins. This means that the `deploy` command must be executed after installing or updating a plugin that provides static resources, or after modifying resources in the `$env/htdocs` directory. This is probably appropriate for most installations but may not be what you want if, for example, you wish to upload plugins through the //Plugins// administration page.

-==== Setting up the Plugin Cache
+==== Setting up the Plugin Cache #egg-cache
 
 Some Python plugins need to be extracted to a cache directory. By default the cache resides in the home directory of the current user. When running Trac on a Web Server as a dedicated user (which is highly recommended) who has no home directory, this might prevent the plugins from starting. To override the cache location you can set the `PYTHON_EGG_CACHE` environment variable. Refer to your server documentation for detailed instructions on how to set environment variables.
+
+If you setup hook scripts that call Trac, such as the Subversion post-commit hook script provided in the `/contrib` directory, make sure you define the `PYTHON_EGG_CACHE` environment variable within these scripts as well.
