@section Integration with Web feeds

@pindex r2e
RSS and Atom feeds could be collected using
@url{https://github.com/wking/rss2email, rss2email} program. It converts
all incoming feed entries to email messages. Read about how to integrate
@ref{Postfix}/@ref{Exim} with email. @command{rss2email} could be run in
a cron, to collect feeds without any user interaction. Also this program
supports ETags and won't pollute the channel if remote server supports
them too.

After installing @command{rss2email}, create configuration file:

@example
$ r2e new rss-robot@@address.com
@end example

and add feeds you want to retrieve:

@example
$ r2e add http://www.nncpgo.org/download/releases.atom
@end example

and run the process:

@example
$ r2e run
@end example

@pindex feeder
But it is more flexible and advisable to use use
@url{https://www.feeder.stargrave.org/, feeder} (NNCP's author creation)
that also transforms feed entries to Maildir email messages. Incoming
entries are placed in @file{new/} Maildir directories, so you can easily
send all of them:

@example
% tar cf - **/new/*(.) | zstdmt | nncp-file - remote.node:feeds-`date -Iseconds`.tar.zst
% feeder/dir/contrib/feeds-oldenize.zsh
@end example

Unlike @command{r2e}, @command{feeder} has also
@url{http://www.feeder.stargrave.org/Enclosures.html, enclosures} and
@url{http://www.feeder.stargrave.org/WARCs.html, WARCs} downloading
capabilities, that are also stored as a files on the disk.
