does anyone know what data is passed to post-processing script?

The automatic email notifications are now working (in 2014) but not really
setup to send to mobile as an SMS. I'm using my ISP's SMTP server to send
an email to my cell carriers email to SMS gateway. The email arrives but is
poorly formatted for SMS.

I have a cmd prompt program that acts as an SMTP client to send fixed text
to my cell, which I use in my pre-processing script fine. I'd like to be able to
send something like

-subj successful;Failed;Action Requested
-data file name of backup file

That tells me what TI is telling me
and what it was operating on.

I don't know if anything is passed, but I guess
since this exit to taken after the log file is closed
it could parsed for the data? I figured if the log file is
a text file; I could grep for the strings I'm looking for?
