OpenLP is now available in the Arch User Repository (AUR). If you are an Arch user I'm sure you are familiar with the AUR, but just in case check out the wiki on the AUR. If you are using Yaourt to install from the AUR a simple 'yaourt -S openlp' will install OpenLP 1.9.3 (Alpha 3). I have used OpenLP some on Arch Linux and I am extremely impressed even using a fairly heavey desktop like KDE, Arch and OpenLP fly.
We would like to think "floft" for making this happen for OpenLP. floft, we would love for you to contact us so we could give you more formal recognition for this great contribution to the OpenLP community.
