[Asterisk-Users] retrieve_?_from_mysql.pl files??

[WipeOut]

Hi,

I was just taking a look at the source code and noticed two files..

retrieve_extensions_from_mysql.pl
and
retrieve_sip_conf_from_mysql.pl

Its pretty obvious what these two files do, but info about them is a 
little scarce..

Is anyone using these scripts and could give me any details on them?

Is there a similar script for voicemail.conf floating about?

Thanks,

Later..
