[Groff] help with mom bibliography

[Anton Shterenlikht]

I'm just starting with mom.
I'm surely doing something wrong.
Please help

TZAV> cat try2.1

Here's Fokion's thesis

TZAV> /usr/local/bin/groff -R -mom -TX100 try2.1
refer:try2.1:7: no matches for `oikonomidis'
try2.1:8: warning: missing number register format
TZAV> 

The output document contains no bibliography at all.
There's only number 1 after the word "thesis", and
even that is not superscript.

Thanks
Anton
