20041012: ACARS

Donna,

The dcgunzip script is in $NAWIPS/bin/scripts and not
the /lsw/wea/gempak/bin/linux/ directory, unless you copied it there.

Since the dcacars.log file isn't being created, it is likely that
either the dcgunzip script isn't found, or the gunzip program
that the script uses isn't being found in the LDM's path
(if that is the case, just hard code the path in the script).

Otherwise, you shouldn't have to....but just in case permissions are
not as expected, make sure the output directory exists and is writable.
I note that I configure the decoders to write to data/gempak/acars,
whereas you are writing to gempak/acars , but I'm assuming that is correct
for your system since the profiler data is being decoded.
