Hi, >There is no such xgettext on my system, do I need to download/install >3rd party tool ?
Yes, to make use of make-messages.py you have to install the gnu gettext utilities. The script uses xgettext, msguniq and msgmerge. And I absolutely don't know wether all this actually will run with Windows at all - I don't have a Windows system to test on, I can only test with Linux and OS X. The problem with the "arg 2 must be 't' or 'b'" should be fixed now, I commited a small change to the utility (adding 'b' to the 'r' in those calls). bye, Georg
