What's feasible to write now, and almost better (but lacking
toolchain/library support) is writing two executables. The first takes
command line options, decides what to do based on them, and then
passes control to the second, with flags set only as appropriate.
Doing this cleanly is OS dependent, and tied to System.Process,
daemonizing-type techniques, and all that. Such a library, possibly
implemented as a nontrivial extension (or borrowing code from) the
excellent-looking hdaemonize package, would be very welcome!
