hi all:

i'm using rpm4 on fedora, i want to implement
a program to generate "recursive dependency tree"
of a certain package.

i know there are some tools to do same thing,
but what i found are all implemented by perl.

i know nothing about perl, i think the time
i study perl is more than the time i write
a new one in python/C.

so can anyone give me some hints to do this
things? such as store dependency relationship
in XML file......

thanks in advance
