- Simple if-else tests a la the C/C++ preprocessor
-
FORMAT variable can be used to test on format, e.g.
- if latex/pdflatex do one sort of code (raw LaTeX)
- if html, do another type of code (raw HTML)
- Easy to comment out large portions of text
- Easy to make different versions of the document
- The mako preprocessor is really powerful - gives a complete programming language inside the document!
