Noweb is a literate-programming tool like FunnelWEB or nuweb, only simpler. 
A noweb file contains program source code interleaved with documentation. 
When noweb is invoked, it writes the program source code to the output files
mentioned in the noweb file, and it writes a TeX file for typeset documentation.
