yes, i read the Makefile.am and xml files. i have two questions left:

1
you wrote the xml files(pk-transaction-files.xml), which is
not generated by tools, right?

2
if the method name is "GetDepends", then your corresponding
functions name must get_depends(), right? and the prefix of
"pk_transaction_get_depends()" is added by:

$(LIBTOOL) --mode=execute dbus-binding-tool --prefix=pk_transaction ...

after you name like this, dbus-glib will add connection
between "GetDepends" and "pk_transaction_get_depends()"
automatically, right?
