20040503: 20040430: archive Level II data and GEMPAK



Robert,

You just have to name the file appropriately
using the file name of the raw file. A script is a good
tool to automate chopping the fields to create the
appropriate output file name.

It isn't practical yo use a file template as with the other decoders
because the CRAFT data is sent in 100 radial bz2 chunks. Any one bz2 piece
does not necessarily have the appropriate information within to determine
the file time, so its not possible to generally read from a pipe
and determine what files the parts go to. So the pqact action
is a single time instance for the output file name.
