I'd like to submit this patch to syslog upstream.  However, though
functional, it's really not in a good form for them to take right now.

The patch is #ifdef'd, so can be enabled at compile time.  Since syslog
ships everywhere and evlog isn't necessarily installed/available
everywhere, syslog would have to leave the #define off by default.  Most
users still wouldn't be able to use the functionality.  So at this
point, getting the patch into syslog upstream means that a user would
still have to get source and recompile syslog to use the syslog -->
evlog mechanism I worked on.

Given all of the above, it will be hard to make a good case to the
syslog maintainers to include it.

I think it needs more work.  It seems to me that when syslog reads it's
conf file, if it sees "%evlog" as a destination, it could do some shared
library magic to see if evlog is available.  If so, it can be loaded and
used.  If not, syslog could generate an error saying that the requested
configuration cannot be achieved.

I have no experience with this sort of "shared library magic".  If
anyone here knows how to do this, that'd be great.  I'd love to improve
this patch to the point where it has a chance to be accepted by the
syslog folks.  I could work with someone, someone could just modify
this, or perhaps someone could point me to an example of this being done
elsewhere (it'd have to be open source for me to look at it).

Anyway, I apologize for the delay in answering.  I would like to submit
this upstream, but think it needs some more work.  Anyone want to help?
