pyautorescene automates the process of returning un-rarred scene releases back into their former glory. It makes use of PyReScene and srrDB to make the whole process has hands off as possible.
With this fork, you can log into your srrDB account to bypass the daily download limit for .srr files. The redirection for srrxx is automatic, so you don't need to worry about it.
It is now also possible to add only NFO/SFV/Sample/Proof/Subs files if you already have scene releases but no longer have the unrarred .mkv files. You can rebuild missing files as long as they are in the same directory.
Additionally, you can search unrarred files by CRC to check if an .srr file is available or if the CRC is valid, for example.
If the script crashes for any reason everything done is print inside autorescene.txt with and without -v.
