//  File:        shutdown.cpp
//  Author:      Francois Revol (mmu_man@users.sf.net)
//  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
//
