09-Dec-2003
First step on factoring out the transport mapping stuff into
loadable modules.
Local stream sockets that check the clients privileges.
03-Dec-2003
Bump version to 1.5 but leave library version intact.
03-Dec-2003
Now works with libbegemot polling stuff instead of libisc.
Use --with-libbegemot[=path] to configure.
03-Dec-2003
Fix parsing of non-minimal ASN.1 integers. They are now disallowed.
Non-minimal lengths are allowed.
Remove copyright clause 3 everywhere.
Make an autoconf build infrastructure.
08-Nov-2003
WARNS=6 fixed.

Installation
------------
You need to apply the patch in the patches directory to your system sources.
This adds a sysctl to retrieve multicast address information from the kernel.
As usual by doing:
make obj ; make depend ; make ; make install
configure [--with-libbegemot[=path]]
make
make install
This does not install a configuration file. The standard location for the
configuration is /etc/snmpd.config, but can be overwritten on the command
line. An example configuration file is provided.

snmpd_mibII:
- handle HC counters by periodically polling the kernel counters.
snmpd_netgraph:
- make some tables writeable
snmpd:
- rethink transports a little bit: make them loadable and make
a private subtree for transports:
OK. Table not writeable yet.
There should be a transport table that is indexed by the transport name.
This table can be used to load/unload transports at run time.
OK. Table not writeable yet.
Then there can be a port table that is indexed by transport name and
port name. Plus a transport-specific table indexed by port name only.
The transport table could contain a column of type OID that points
to the transport-specific table.
