International APPs / pygettext

[Ingo Linkweiler]

... and what to do now?

I have replaced some strings by _("string"), and started pygettext.
The result was a "messages.pot" file like this:

#: PyNassi.py:121
msgid "&New Editor"
msgstr ""

Where can I add the translations?
And what´s the next step?

"msgfmt" needs a ".po"-file, not a ".pot" file.

What can I do, when some smaller changes are made on the source file? Is 
it possible to "update" the translation files without creating a new one?
