Lotus Symphony wiki
Well, good job IBM! Bout damn time -- not only did it show up right away in the repositories, but it even updated the older Symphony 1.2 installation that I had installed earlier.
One problem, though -- when I initially tried to open Symphony 1.3, the program exited without doing anything. Wondering what was going on, I typed "symphony" from the command line to see, and it was apparently IBM's text-based EULA for Symphony that was failing to show up, and thus not allowing Symphony to start.
IBM really, really needs to change that text-based EULA into something else. :P
