AST means Abstract Syntax Tree, which is basically an abstract representation of code / any syntactic structure. A transformation is an action modifying this tree (i.e. transforming the existing AST to a new AST). For more information have a look here: http://en.wikipedia.org/wiki/Abstract_syntax_tree
