# Regarding usage of the arch logo, I asked in #archlinux on irc.freeode.net on
# Friday,  May 25th 2012 , around 12:00 CEST

#11:59 < matthiaskrgr> I made a script which visualizes the pacman logfile (package updates removals etc)
#12:00 < matthiaskrgr> looks like this http://www.youtube.com/watch?v=lCBjzC78t4o
#[...]
#12:00 < matthiaskrgr> and I wondered if I was allowed to display a little arch linux icon at the lower right corner
#12:00 < allanbrokeit> I had seen that on the forums
#[...]
#12:00 < matthiaskrgr> or if there were any problems with it
#12:00 < allanbrokeit> matthiaskrgr: I'd say that is fine
#12:00 < matthiaskrgr> ok thanks :)
#12:01 < matthiaskrgr> I'll quote you in some code comment, just in case... ;)
#12:01 < allanbrokeit> matthiaskrgr: https://wiki.archlinux.org/index.php/DeveloperWiki:TrademarkPolicy
#[...]
#12:02 < allanbrokeit> I'd say this falls in the advocacy section
