Epylog is a log analysis code written by Konstantin ("Icon") Ryabitsev, when he was working Duke University in the early 2000's. It was moved to FedoraHosted and then never got moved to other hosting afterwords. The code is written in early python2 syntax (maybe 2.2) and has been hacked to work with newer versions over time but has not seen any major development since 2008. I have been sort of looking after the package in Fedora with the hopes of a 'rewrite for Python3' that never got done by me. [This is on me as I have been licking the cookie here.]
Because it requires a lot of work, and Python 2's End of Life is coming up in a year, I retired it from rawhide so that it would not branch to Fedora 30. I would recommend that users of epylog look for newer replacements (we in Fedora infrastructure will be doing so and I will post any recommendations as time goes by).
