 * Important Notes
 *   When in pagination mode (&paginate = 1) always call the snippet uncached in the [!NewsManager!] format
 *   Also, in pagination mode, make sure to use the placeholders for navigation!
 *   To display tv's make sure you use the tv prefix! 
 *   For example, if you have the template variable author you would put [+tvauthor+] in your template.
 *
 * Snippet placeholders:
 *   [+sepchar+]    - separator between a document URL and parameters
 *                    (for example [~[*id*]~][+sepchar+]param1=value1&param2=value2)
 *   [+editformid+] - Id of page to use for editing a post
 *   [+pagetitle+]  - current post's page title
 *   [+longtitle+]  - current post's article title
 *   [+id+]         - current post's id
 *   [+edit+]       - text for edit action
 *   [+delete+]     - text for delete action
 *   [+show+]       - text for show action
 *   [+refresh+]    - text for refresh action (update the creation date to now so the post is first in the list)
 *   [+hidemenu+]   - text for hide menu action or show menu action (dependent of the current state of the post)
 *   [+pubish+]     - text for publish action or unpublish action (dependent of the current state of the post)
 *   [+next+]       - text for next action
 *   [+previous+]   - text for previous action
 *   [+prevnextsplitter+] - splitter if always show is 0
 *   [+pages+]      - page list
 *   [+totalpages+] - total number of pages
 *   [+start+]      - the # of the first item shown
 *   [+stop+]       - the # of the last item shown
 *   [+total+]      - the total # of items on the page
