./makexpi.sh fails when pkg directory doesn't exist
Here's the problem:
~/torbutton$ ./makexpi.sh
---------- create torbutton.jar file ----------
---------- create torbutton.xpi ----------
zip -X -9r ../pkg/torbutton-1.6.9.0.xpi ./ -x chrome/* -x *.diff -x *.s
zip I/O error: No such file or directory
zip error: Could not create output file (../pkg/torbutton-1.6.9.0.xpi)
(Patch to be posted shortly.)
