Literate Programming

• Basic Idea: Combine Documentation and Source Code
• WEB (Donald Knuth, of TEX fame)
  • Weave: web file $\longrightarrow$ documentation (TEX)
  • Tangle: web file $\longrightarrow$ source code (Pascal)
• Many others, most based on WEB:

  AWEB	Ada	?	?
  CLiP	Any	Any	written in Pascal

• My opinion: most are too complex or don't support my situation (F90, L^ATEX, Unix)
