[rt-users] --summary format

[Percynski, Fred]

Is information available on how to format the --summary option in RT's
command line interface?  From reading the archives I know that RT supports
this
--summary %id4%queue10%subject40
but I am trying to figure out a way to delimit each field, something like
--summary %id4 : %queue10 : %subject40

Any ideas on how to do this?  Specifically, how to delimit each field so
that Perl can parse the information easily.

Thanks!
Fred
