How do I list the contents of an archive?

First, if the archive isn't already open and started up

RSS$source <- SEASCANARCH$get.ports()[[1]]                ## make the source a seascan archive reader

config(RSS$source, filename="c:/data/myseascanarch.dat")  ## set the filename
start.up(RSS$source)

Then, get the contents:

get.contents(RSS$source)     ## a list with start/end times and numbers of scans for each segment
