Initial commit
Not entirely sure what all I might put here, but for now there's a
Makefile with install and uninstall targets, the script fragment
sfeednew, a README, and example sfeedrc.

+This project provides the ability to access newly merged sfeed items
+by redefining sfeed_update(1)'s merge function.
+
+You could use this for in many ways, but I use it to send an email
+with a summary of the new items to keep from having to open
+sfeed_curses(1). An example of this is shown in sfeedrc. (Another
+possibility would be to use sfeed_mbox(1) on the new items and
+incorperate it into your mail, but I find sfeed_curses(1) is
+preferable to my current mail client for looking at feeds.)
