Lipsum is a command-line utility for literate programming. It stands in the tradition of Noweb, a popular and flexible literate programming system by Norman Ramsey. The idea of literate programming is to keep documentation for programmers and program code in one file and to arrange it in a way that helps understanding it best. To actually compile or run the code it needs to be extracted from the literate program and Lipsum is a tool to do this.
Like Noweb, Lipsum employs a minimal markup to arrange documentation and code in a file. Also like Noweb, Lipsum is language agnostic and can be used for almost any programming language and documentation.
