I wrote a tool a while back called "relogger.pl" which takes an existing
syslog data file and re-injects each line back into syslog.  It was meant
for testing logsurfer or anything else that parsed syslog data, so you
could have a "test" stream of log data sent in real-time.  It's basically
the same idea as logger, but it parses the data and can do things like
figure out the delay between two messages and simulate the delay when
re-logging the message.

It almost does what you want - except right now it only reads
syslog-formatted files.  You'd have to teach it how to deal with normal
text files, and then add parsing for the data in question - maybe add a
command line option like:

   "--facilitymatch /PATTERN/=crit" (if data matches PATTERN, syslog it
with facility "crit").

relogger.pl is attached.
