When I invoke vinagre --help it shows unlocalized strings from gtk-vnc.
I'd like to i18n the help option.
I'm attaching the patch.
After attach the patch, intltoolize need to be run.
libtoolize -f
intltoolize --automake --copy --force
aclocal
autoconf
automake -a -c -f
./configure
Patch for Makefile.am, configure.ac, po/LINGUAS, po/POTFILES.in src/Makefile.am, src/vncdisplay.c
