=======================================
Usage 2: PEEKCAT /m source.txt newfile
Concatenates all .pkt files listed in source.txt and outputs
to newfile. source.txt is a text file with each file listed
on a single line. dir /b *.pkt > source.txt is one way to
produce this file.
Options: /s : merge sort the packets by timestamp (slower)
/e : eliminate duplicates when sorting
EXAMPLE 2: peekcat /m source.txt newfile.pkt
Combines 1.pkt, 2.pkt, 3.pkt, and 4.pkt into newfile.pkt.
