Reference title

Reference topics document programming constructs or facts about a product. Examples of reference topics include language elements, class descriptions, commands, functions, statements, protocols, types, declarators, operands, and API information, which provide quick access to facts, but no explanation of concepts or procedures. For instance for the SVN Client this is the command line:

svn export --revision rev URL PATH
Type Value Description
rev Specifies the desired revision(if necessary).  
URL   Repository URL you want to export from.
PATH   Location on the file system where to export.
