   2 Modern based cms theme
   3 ======================
   4 
   5 If you want to use a wiki as a tool to create a regular site easily,
   6 this theme is for you. The wiki looks like a plain site to visitors or
   7 users without edit rights, and a wiki to users with edits rights. 
   8 
   9 This is also a replacement for the readonly theme that was part of release 1.2.
  10 
  11 
  12 Problems
  13 --------
  14 Some actions are not available for visitors:
  15 
  16 - Show Raw Text
  17 - Show Print Preview
  18 - Show Like Pages
  19 - Show Local Site Map
  20 - Delete Cache
  21 
  22 Most of these are not really needed for a visitor. Print style sheet is
  23 used transparently when you print a page. Like Pages and Local Site Map
  24 should be available, but are not really needed if you have a good
  25 search.
  26 
  27 Missing page will suggest visitors to create a new page, but they will
  28 always fail because they don't have acl rights. This should be fixed in
  29 other place.
  30 
  31 
  32 Install
  33 -------
  34 
  35 1. Put in your wiki/data/plugin/theme/
  36 
  37 2. Prevent visitors from writing using acl::
  38 
  39     acl_rights_before = (u"WikiAdmin:read,write,delete,revert,admin "
  40                          u"EditorsGroup:read,write,delete,revert ")
  41     acl_rights_default = u"All:read "
  42                           
  43 Remember that some ACL you put on a page will override the default ACL!
  44 
  45 3. Make it the default and only theme on your site::
  46 
  47     theme_default = 'modern_cms'
  48     theme_force = True
  49     
  50     
  51 Compatibility
  52 --------------
  53 Tested with release 1.5.1, should work with any 1.5 release.
