Custom Twitter timeline rss feed after v1 API retirement

So Twitter has decided to retire its v1 API, breaking everybody's timeline rss feeds (which I happened to use for my blog). Fortunately my twitter client (znc on top of bitblee) logs all my tweets to a text file so create my own rss feed is almost trivial (I haven't bothered to correctly link my tweets though. I plan to eventually migrate away from twitter anyway).

grep -h '<markus>' .znc/users/markus/moddata/log/\#twitter_lemmster_*.log \
> foo.tmp && tac foo.tmp | head -3 | sed 's/<markus> //g' | \
~/bin/lines2rss.sh 'tweets' 'http://www.lemmster.de' 'whatever' \
> /var/www/tweets.xml
