About the files in the phex_0.5.0.zip:

- the src.zip simply contains the original uncompiled java-sources of Phex. They have to be included in the distribution because of the GNU GPL. You can even delete them if you like. All other files should rather not be touched at all.

About the comparison:

- this is fascinating, I will have to discuss this with the developers.
(But at least the new internal search engine is working!)
