where is snmp_mgr in otp_src_R10B-9?

[Daniele Andreasi]

Hi,
     I'm using erlang snmp and i'd like to test my agent development 
with snmp_mgr, but i don't find that module in erlang src and library.
Moreover I find in the directory ex1 in the snmp library an example 
where the module snmp_mgr it's started by the module snmp_mgr_tests...

How it's possible?

Thanks
Daniele
