Concordance has finally made it's way into Fedora!
I've been maintaining packages separately from Fedora for awhile now; the review has been there since October 2007! Unfortunately there were some legal concerns about the trademark over the name of the project ("harmony") originally, then when 0.20 was finally released with a new name the package required some work since the library was split off from the cli. At any rate, if you need to program your remote from Fedora, all you need to do is:yum install concordance
