Guys i have a question for ya... well if i caompile for example rev 2014 and after two days there comes a new rev 2015 with new fixes what should i do? as i know i have to download a file called diff.file wich has the newest changes/fixes . but what should i do with this file and how to addapt it? :/

To apply that diff file you can use either eclipse or tortoise svn depends on what you use to download and compile program...it is easy to add the diff file, but if you have custom codes there can be conflicts that have to be fixed manually.

alright and after compiling this diff which files i set on my already running live compiled pack?

do you mean update the pack?

yeah

after you download the diff file go on your eclipse end press apply/team/team path

thats all

team - > update to head revision
