no, because
a) It is in IO
b) There might be reasons to toss around commands for other programs.
Assume you would, for some reason, have a suite of darcs related
programs, and want to generate manpages for all of them in one place.
Then being able to handle DarcsCommands of different executables would
help.
b) is quite hypothetical, but a) is a selling point IMHO :-)
Greetings,
Joachim
