The ew2file program
will take any message from a ring and write it to a file in a specified
directory. The Earthworm message is written verbatim (in binary form)
and is thus not generally readable. It writes timestamps on the files
if the packet type is one of TYPE_PICK2K, TYPE_PICK_SCNL, or
TYPE_HYP2000ARC and the TimeBasedFilename flag is set in the .d file.
This module can be used in conjunction with sendfile/getfile to send
messages as files. Its counterpart is file2ew.
