// Tag Definitions

// Following information is necessary for a BBCode tag:
//   tag          how the [tag] is named
//   htmlopen     what it's to be translated into (parameters used by $1, $2...)
//   htmlcont     new content inside the HTML tags, normally something like $1, $2...
//   htmlclose    closing HTML tag (optional)
//   htmlblock    this defines its own block, new-lines around it are removed
//   maxparam     number of parameters for BBCode tag
//   openclose    has a closing tag, $htmlclose is needed
//   nocase       case-insensitive tagname (default, recommended)
//   nested       may this tag be nested? ex. [b]...[b]...[/b]...[/b]
//   proccont     process the tag's content? if no, nested is ignored
//   subset       what subset this tag belongs to

// Maximum parameter count is currently set to 3. You might want to change this.
// Relevant code locations are marked with MAXPARAM.
