   4     The StaticPages plugin allows you to put some .html or .php files
   5     into dedicated directories, which then will get available with their
   6     basename as ewiki pages. The files can be in wiki format (.txt or no
   7     extension), they can also be in .html format and they may even contain
   8     php code (.php).
   9  
  10     Of course it is not possible to provide anything else, than viewing
  11     those pages (editing is not possible), but it is of course up to you
  12     to add php code to achieve some interactivity.
  13     The idea for this plugin was 'borought' from http://geeklog.org/.
  14  
  15     In your static page .php files you cannot do everything you could
  16     normally do, there are some restrictions because of the way these static
  17     pages are processed. You need to use $GLOBALS to access variables other
  18     than the $ewiki_ ones. To return headers() you must append them to the
  19     $headers[] or $ewiki_headers[] array.
  20  
  21     If you define("EWIKI_SPAGES_DIR") then this directory will be read
  22     initially, but you could also just edit the following list/array of 
  23     directories, or call ewiki_init_spages() yourself.
