Our DMS Reengineering Toolkit parses arbitrary langauges ("domains"),
builds ASTs (capturing all the lexical source information such as
comments, number formats, etc.), can apply source-to-source
transformations to the trees, and finally prettyprint the result.
This is driven by a "domain definition" including a grammar and
prettyprinting rules.

DMS works for many langagues, including C++ and Java. If you don't do
any transforms, this is just prettyprinting. (This is direct evidence
of the existence of a C++ prettyprinter :) What goes out is exactly
what comes in, modulo nice indentation and line breaks according to
the language rules.

The domain designer has complete control over how lexemes are
reconstructed during prettyprinting, so one can easily normalize case
or choose certiain lexical formats (e.g., force all floating point
numbers to be printed in scientific notation, say).

Addition of extra "comments" marking off sections of the text as shown
in the example below would be accomplished by simple transforms. Lots
of interesting variations of "prettyprinting" are possible with modest
transforms, including generation of "xxxdoc" (pick your favorite)
annotations of the source.
