...especially given that the default ("-T text") output of TShark is designed for humans, not programs, to read. If your program can read it, great, but if it's easier for it to read PSML or PDML....

(Yes, I know about the UNIX philosophy with respect to program output. At times, it can lead to output that's suboptimal for humans to read but not *quite* as parsable by software as one might like, i.e. it can sacrifice human readability without gaining sufficient program readability to make up for it - sometimes you might as well just have two separate formats and be done with it.)
