Hello list.
I'm trying to compile ghc 6.12.1, but the documentation part fails because
dblatex can't escape all the backslashes that it should. (I've tried
dblatex-2.10, -2.11 and -2.12.)
A similar problem has been discussed earlier [1], but even with Christiaan's

Hi everybody,
I'm very excited to announce the first release of Yi in nearly a year. For
