How to compile/merge more than one .po file with Mallard?

[Juliette Tux <juliette tux gmail com>]

Hello everybody,

I represent Russian translation team and currently I'm working with GNOME help files and Mallard. These are my first steps with Mallard, so I'm asking for help. 

As I can see, (judging by the text which appears in the default help opened woth yelp), the big global GNOME help takes more then one .po file to compile. These are: the one from gnome-user-docs/gnome-help, the one from gnome-getting-started-docs and at least one more file regarding the Privacy settings, but I wasn't able to locate the corresponding files in the git, yet. I guess it was just recently added, correct me if I'm wrong.

So my question is: how do I compile/merge more then 1 .po file into one help document to view it with yelp. Currenty I'm using the following string to work with single .po:

for i in *.page; do xml2po -m mallard -p ../ru.po $i > ../tmp/$i; done

And the '*.po' instead of 'ru.po' gives an error Error: You can merge translations with only one XML file at a time.

Thanks in advance!
