+1.3/ pytz fixup to work in an executable package
+
+pytz needs runtime access to timezone definition files.  pytz is hard-coded to search in the directory from which the pytz .py modules are being run.
+In a py2exe package, this directory is actually a library.zip container file, so windows cannot find the timezone definitions, and will crash the app.
+
+We need to make a one-line change to pytz to search in the current working directory (which is not a container), and not the application directory.
+The py2exe script copies the timezone datafiles into the package folder pyfpdb/zoneinfo.
+
+Thanks to Jeff Peck <peck.jeff <at> gmail.com> on the py2exe mailing list for documenting this problem and solution.
