Description:
Regression test system for font-lock
Emacs is capable of highlighting buffers based on language-specific `font-lock' rules. This package, `faceup', makes it possible to perform regression test for packages that provide font-lock rules. The underlying idea is to convert text with highlights ("faces") into a plain text representation using the Faceup markup language.
