Message #22146
[Merge] lp:~trb143/openlp/refactor into lp:openlp
Tim Bentley has proposed merging lp:~trb143/openlp/refactor into lp:openlp.
Requested reviews:
Raoul Snyman (raoul-snyman)
For more details, see:
https://code.launchpad.net/~trb143/openlp/refactor/+merge/193146
This is work in progress and not complete.
This is a start to add trace functionality and clean up logging.
Move de_hump as it has more uses than theme!
add register decorator.

https://code.launchpad.net/~trb143/openlp/refactor/+merge/193146
Your team OpenLP Core is subscribed to branch lp:openlp.
