aclocal
automake --add-missing
autoconf
./configure 

Special options to configure:


--with-confdir=name     Set the pathname of the logdigest configuration directory
			(defaults to /etc/logdigest/)

--with-tmpdir=name      Set the pathname of the logdigest temp directory
			(defaults to $prefix/var/lib/logdigest)


Configuration:

For the regular expressions (that constitute the "filter rules"), 
edit /etc/logdigest/ignore.local (a file that is empty in the beginning).

See /etc/logdigest/ignore for examples.  The character '.' is an arbitrary
character, the characters (|)[] have special meaning unless escaped with '\',
and so on.

For testing, you can simply use 
grep -f /etc/logdigest/ignore.local /var/log/messages
(or grep -v -f for the negative match).

Note: /etc/logdigest/ignore.local must not contain emty lines!
