Hey Tony!

 TL> It takes me a little while to understand the nuances of scripts.

Sounds great.  I had to liberate the posted parts from a bash function file
that I source from other script(s) so I fully appreciate your point.  ;-)

Anyhow take your time and if you have any questions/suggestions I am all ears.

 TL> but do we want to keep track of any individual components such as
 TL> headers, kludge lines, etc?

Yes we do.  That is the goal and other than possible splitting of the kludges
from the msg_body (fifth field) I believe the current format is a very good
foundation.  We may wish to translate the nulls to a more suitable control
code, such as the aptly named 'field seperator' (aka 0x1c) but gawk doesn't
seem to mind nulls if indeed we find gawk to be a keeper in scripting.  bash
string handling has improved over the years and might be fun to replace sed
and tr calls ... if indeed we want to.

 TL> you might need to modify the format a bit

No doubt.  Still I think it is a solid foundation to build from but I will
wait for your later assessment.

Life is good,
Maurice
