==Usage==

DMS has been used to implement a wide variety of practical tools, include [[___domain-specific language]]s (such as code generation for factory control), test coverage<ref>[http://www.semanticdesigns.com/Company/Publications/TestCoverage.pdf Branch Coverage for Arbitrary Languages Made Easy]</ref> and profiling tools, [[Duplicate code|clone detection]],<ref>[{{Cite web |url=http://www.computer.org/portal/web/csdl/doi/10.1109/ICSM.1998.738528 |title=''Clone Detection Using Abstract Syntax Trees''.

The toolkit provides means for defining language grammars and will produce [[parser]]s which automatically construct [[abstract syntax trees]] (ASTs), and [[prettyprinter]]s to convert original or modified ASTs back into compilable source text. The parse trees capture, and the prettyprinters regenerate, complete detail about the original source program, including source position, comments, radix and format of numbers, etc., to ensure that regenerated source text is as recognizable to a programmer as the original text modulo any applied transformations.
