    00009  *     Revision 1.1  2006/05/19 16:55:02  paulf
    00009  *     first inclusion
    00009  *
    00010  *     Revision 1.5  2001/04/12 03:47:36  lombard
    00011  *     revised putaway include files; cleaned up some comments
    00012  *
    00013  *     Revision 1.4  2001/03/28 04:50:27  lombard
    00014  *     ripped out the junk that was attempting to multiplex traces.
    00015  *     It works much better now, and uses less memory.
    00016  *
    00017  *     Revision 1.3  2000/09/20 18:06:24  lucky
    00018  *     Removed fixed number of MAX_MSGS. Instead we allocate as many
    00019  *     slots for messages as our max buffer can hold, and we remember
    00020  *     that number so that we can free at the end.
    00021  *
    00022  *     Revision 1.2  2000/03/10 23:19:03  davidk
    00023  *     changed the tankputaway interface to match the new PA interface in
    00024  *     putaway.c
    00025  *
    00026  *     Revision 1.1  2000/02/14 18:51:48  lucky

    00036         These routines are called from putaway.c. They implement writing
    00037   selected trace data into files which can be read by tankplayer.

    00040 /*
    00041   Tank putaway routines revised to make them work. The idea now is simple:
    00042   Write a single file containing all the TRACEBUF messages for one SCN,
    00043   followed by all the TRACEBUF messages for the next. The order of the
    00044   SCNs or TRACEBUF messages doesn't matter.
    00045   Then to make this into a tankplayer file, use Lynn Dietz' remux_tbuf
    00046   program, currently in Contrib/Menlo.  Pete Lombard, MArch 2001
