COPYING.LIB:
  This is a copy of the GNU LGPL, which covers sig.h and sig.c, used by
  logmonitor.c.

apvsync.c:
  provides synchronization between listen.tcl (which produces volumes
  on disk) and archiver.pl (which consumes them).
  
logmonitor.c:
  writes its standard input to a file, reopening the file
  whenever it receives a certain signal.  The wrapper scripts
  pilot/archiver.sh and pilot/pilot.sh pipe the output of
  archiver.pl and pilot.tcl to logmonitor to write log files, so that
  newsyslog can signal logmonitor when rotating the log files. (On Linux, the
  program corresponding to "newsyslog" is "logrotate".)

spit.c, spit.c:
  The spit utility attempts to generate traffic consisting of ethernet frames
  of a specified size at a specified rate.  These ethernet frames do not
  really contain true IP packets, but their contents look enough like IP
  packets to fool the vault into archiving them.  Some control over the IP
  addresses put in the fake IP packets is also provided, to test the vault
  in open headers mode.  Running spit on a network that is used by anyone
  else would be extremely obnoxious.
