## Rules to auto-generate translated XML files
##
## At first, you need to install `xml2po' package maintained by
## GNOME team, too bad it's not a separated package (and depends
## libxml2 >= 2.5.11), to get a workable package, try the following
## steps:
##
##    cvs -d:pserver:anonymous@anoncvs.gnome.org:/cvs/gnome login
##    (RETURN)
##    cvs -d:pserver:anonymous@anoncvs.gnome.org:/cvs/gnome co \
##      gnome-doc-utils/xml2po
##    cd gnome-doc-utils/xml2po && ./autogen.sh && make
##
## For developers: Nothing, you need nothing to do basically,
##   however it's appreciated if you'll install the package above,
##   keep updating POT, PO files when you'll update your documents.
##
## For translators: Just translate your PO file with your favorite
##   editor, if you see no PO file for your language, then type
##   `msginit' in this directory and enter your contact address.
##
## For maintainers: You're supposed to watch every changes made
##   by the developers, translators; if POT, PO files are out-of-
##   dated or generated XML files are committed properly.
##
## A problem could be the matter is, it takes a time to update
## entire files due to its size and processing method in general
## (comparing with the gettext PO files), also with the same
## reason, it costs a certain disk spaces against the repository.
