-.Os
-.Sh NAME
-.Nm sfeed_tail
-.Nd format unseen feed data to a plain-text list
-.Sh SYNOPSIS
-.Nm
-.Op Ar file...
-.Sh DESCRIPTION
-.Nm
-formats unseen feed data (TSV) from
-.Xr sfeed 1
-from stdin or
-.Ar file
-to stdout as a plain-text list.
-If one or more
-.Ar file
-are specified, the basename of the
-.Ar file
-is used as the feed name in the output.
-If no
-.Ar file
-parameters are specified and so the data is read from stdin the feed name
-is empty.
-.Pp
-.Nm
-will mark the initial items on the first run as seen.
-Then it will print the initial items if data is read from stdin, if the data
-is read on the first run by specifying the argument(s)
-.Ar file
-it will not show the initial seen items.
-.Pp
-Unseen items are printed per line in a similar format to
-.Xr sfeed_plain 1 ,
-duplicate items are ignored.
-The list of unique items is determined by the fields: feedname, item id and
-UNIX timestamp of the item date.
-.Sh IMPLEMENTATION NOTES
-Keep in mind that because
-.Nm
-keeps a list of all the items it can consume much memory.
-.Sh SEE ALSO
