ML/I

ML/I is a general purpose macro processor with a history going back all the way to 1966. It best known for its powerful text processing features that lead to it being primarily used on one one hand for processing human readable text for reformatting purposes and on the other as a pre processor for programming code where code needed to be translated between programming languages that had some structural similarity but different syntax. While old and rarely updated it still has some advantages over more modern processors such as M4 or PPWizard or programming languages like AWK as it has better support for nesting and long lines of text.
