Hi,
It works very well, both for translating Alfresco Explorer and Alfresco Share. I'm just finishing up for Labs 3 Stable, done some intial testing.
But the guide might be a bit out of date, I plan to update the guide and put it in the wiki (when time permits)
So what to translate? When you check out the Swedish project, it will also check out files directly from the Alfresco subversion HEAD code, using externals. If you do not get anything under the source directory, make sure your subversion checkout/update is set to pick up externals. Then just start OmegaT and it will pick up the files in source.
Note that the external references for Share picks up a lot of other files thant just properties files, these will however be ignored by OmegaT and not part of the translation. So just start translating, all the files need translating for a complete translation. But some are more "administrator" oriented, and you may choose to translate them last or ignore completely. I would start with webclient.properties.
To build, it is a 2 step process. First, run OmegaT and select the option "Create Translated Documents". Then run the build script using ant. I have only tested the build script on my linux box, so for windows I guess you first need to install ant. You can chekc in the build.xml what it actually does.
Hope this helps for now.
