    2 Processors are WikiMacros designed to provide alternative markup formats for the Trac Wiki engine. Processors can be thought of as ''macro functions to process user-edited text''.

    4 The wiki engine uses processors to allow using [wiki:WikiRestructuredText Restructured Text] and [wiki:WikiHtml raw HTML] in any wiki text throughout Trac.

    68== Using Processors ==
    7 To use a processor on a block of text, use a wiki blockquote, selecting a processor by name using ''shebang notation'' (#!), familiar to most UNIX users from scripts.

     28Note that since 0.11, such blocks of HTML have to be self-contained, i.e. you can't start an HTML element in one block and close it later in a second block. Use div or span processors for achieving similar effect (see WikiHtml).
