Comment (by guest):
just so that this doesn't get lost: there's a simple xslt file to extract
text for a --full-flag-help option here
http://www.haskell.org/pipermail/cvs-ghc/2007-September/038560.html
it is simpler than the one for man pages, using sed to define the missing
ENTITY references, and it brings each flag onto a single line, making it
ideal for grep.
now, for a first implementation of --full-flag-help, just generate the
text file when creating a release/snapshot, install in `ghc --print-
docdir`, and make the flag print the file (for bonus points, build in the
pattern filter for those who don't have grep/awk at hand, so that --full-
flag-help "interactive mode:" gives the ghci flags, and
"language:instances" gives the language flags related to instances).
