Sorry, I forgot to put it into the documentation. It's now available from 
http://midas.psi.ch/elog/config.html You basically use "Execute new = 
<command>", where <command> can have substitutions like $<attribute>, 
$remote_host, etc. You also have to start elogd with the "-x" flag to enable 
shell executions, since they can impose a security problem (see documentation).
