The file pathetc/nntpsend.ctl specifies the default list of sites
to be fed by nntpsend. Comments begin with a number sign (#) and
continue through the end of the line. Blank lines and comments are ignored.
All other lines should consist of four fields separated by a colon.
The first field is the name of the site as specified in the newsfeeds
The second field should be the hostname or IP address of the remote site.
The third field, if non-empty, specifies the default head truncation size
of the batch file. If this field is empty, no truncation is performed.
This field may be of the form maxsize-truncsize, in which
case it is passed to shrinkfile as -m maxsize -s truncsize; otherwise it is of the form truncsize, in which case it is
passed as -s truncsize.
The fourth field specifies some default flags passed to innxmit. Note
that the flag -a is always given to innxmit and need not appear here.
If no -t flag is given in this field or on the nntpsend command line,
-t 180 will be given to innxmit.
See nntpsend(8) for an example of nntpsend.ctl config file.
