/**
* @defgroup pathauto Pathauto: Automatically generates aliases for content
*
* The Pathauto module automatically generates path aliases for various kinds of
* content (nodes, categories, users) without requiring the user to manually
* specify the path alias. This allows you to get aliases like
* /category/my-node-title.html instead of /node/123. The aliases are based upon
* a "pattern" system which the administrator can control.

<h2>Settings</h2>
<p>The <strong>Maximum Alias Length</strong> and <strong>Maximum component length</strong> values
default to 100 and have a limit of 128 from pathauto. This length is limited by the length of the dst
column of the url_alias database table. The default database schema for this column is 128. If you
set a length that is equal to that of the one set in the dst column it will cause problems in situations
where the system needs to append additional words to the aliased URL. For example... URLs generated
for feeds will have "/feed" added to the end. You should enter a value that is the length of the dst
column minus the length of any strings that might get added to the end of the URL. The length of
strings that might get added to the end of your URLs depends on which modules you have enabled and
on your Pathauto settings. The recommended and default value is 100.</p>
<p><strong>Raw Tokens</strong> In Pathauto it is appropriate to use the -raw form of tokens. Paths are
sent through a filtering system which ensures that raw user content is filtered. Failure to use -raw
tokens can cause problems with the Pathauto punctuation filtering system.</p>');
