// File: shutdown.cpp
// Author: Francois Revol ([email protected])
// Description: shuts down the system, either halting or rebooting.
//
// Notes:
// This program behaves identically as the BeOS R5 version, with these
// added arguments:
//
// -a alert user while counting down
// -c cancels any running shutdown
//
// There seem to be a race condition (sometimes crashes on quit with
// "the looper must be locked"), if you find it, tell me,
// tried 3 hours to find it.
// Some code from Shard's Archiver from BeBits (was BSD/MIT too :).
//
// Compile with: LDFLAGS="-lbe" make
//
