Infos about sysklogd and syslog-ng ?

[melodie]

I was wondering what become with the old programs that are the basis of the Linux distros, and if the two said programs are supposed to fill the same target ?

To compare closer if some of you are interested, this is the version which we use actually, it is the latest available:
http://www.infodrom.org/projects/sysklogd/download/sysklogd-1.5.tar.gz

here is the link to the last syslog-ng sources:

The website "balabit.com" is very business oriented... :/
