Subject: [PATCH] *) correcting problems with wrong svn revision number - if
 the .svn directory exists, the entries file will be   parsed to determine the
 revision number of the corrent   working copy - then the revision number in
 the build.properties file   will be overwritten with this value - if the .svn
 directory does not exists the value from   the build.properties file will be
 used
