Message #11296
[Merge] lp:zorba/info-extraction-module into lp:zorba
Pedro Miguel Antunes has proposed merging lp:zorba/info-extraction-module into lp:zorba.
Requested reviews:
Zorba Coders (zorba-coders)
For more details, see:
https://code.launchpad.net/~zorba-coders/zorba/info-extraction-module/+merge/111723
CMakelists.txt has been added for the project and I have managed to build the module separately and together with Zorba.
The test directories have been fixed, and the results now have the appropriate .xml.res extension.
The test queries have been fixed and no longer have references to a folder in my computer.
The .DS_Store files have been removed from the branch.

https://code.launchpad.net/~zorba-coders/zorba/info-extraction-module/+merge/111723
Your team Zorba Coders is requested to review the proposed merge of lp:zorba/info-extraction-module into lp:zorba.
