Thank you, guys, a lot, but I'm not going to return to releases =)

erlyvideo is just a plain unix software, like apache or sendmail, that is

They can modify only one file in /etc/, so I need to read it before
startup. But there may not be this file, so I need to look for in in other

I really don't see any use in releases for me, so my way of configuring

_working_. Working in  _my practice_.
