.SH FILES READ
.TP
.B sfeedrc
Config file, see the sfeedrc.example file for an example.
This file is evaluated as a shellscript in sfeed_update.
You can for example override the fetchfeed() function to
use wget, fetch or an other download program or you can
override the merge() function to change the merge logic.
The function feeds() is called to fetch the feeds. The
function feed() can safely be executed as a parallel job
in your sfeedrc config file to speedup updating.
