CHANGES from 1.2 to 1.3
=======================
Fixed argument passing to slip.login for dynamic address thanks
to Johann Visagie.

CHANGES from 1.3 to 1.4
=======================
Added more comments and fixed setsid().

CHANGES from 1.4 to 1.5
=======================
Security fixes thanks to Michael O'Reilly.

CHANGES from 1.5 to 1.6
=======================
Sliplogin no longer forks. Please report if this causes any trouble.
These changes are made by Jon Lewis:
Changed output messages to deal with stupid windows clients.
Added 2 seconds delay.
Added a default user.

CHANGES from 1.6 to 1.6.1
=======================
Added a fflush() call after the output message to force
printing.

CHANGES from 1.6.1 to 2.0
=========================
Now sliplogin watches the incoming IP traffic if you activated the /proc
filesystem. This means you can specify a timeout while the slip client
must send something through the slip interface or sliplogin will terminate
the slip session. This feature is pretty untested since i lack the
equipment so report bugs asap, please. The side effect of this is
that slip.hosts needs the new timeout value to be set.
Another new feature is brought to you by Dick Porter. Sliplogin now
supports NIS (YP) tables. You can put slip.hosts on a NIS server
and sliplogin will search in the NIS table for the user entries instead
of /etc/slip.hosts.
Last but not least sliplogin writes the total sum of sent and received
packets in the syslog file (if possible).
Read the manual on how to use the 2 new (optional) features.
A few more options have been added in the Makefile.
Update your old slip.hosts.

CHANGES from 2.0 to 2.0.1
=========================
Though i didn't receive a bug report, i discovered that sliplogin
didn't use the NIS entry. This is hopefully fixed now.


Changes from 2.0.1 to 2.0.2
===========================
Security fixes thanks to Olaf Kirch <okir@monad.swb.de>.

Changes from 2.0.2 to 2.1.0 (by jan@todonix.ping.de)
===========================
- Merging sliplogin & esliplogin

- usage of '*' or 'DYNAMIC' for dynamic adressing

- dynamic addressing of local address (always ignore 
   local address field with compile time option DYNAMIC_SERVER. Usefull
   if you want to use old configuration scripts at several servers.)

- Merging slip.login & slip.logout
  (Warning: don't use old scripts, the number of arguments has changed!)

- Easy configuration of subnets with slip.route

- additional compile-time option SLIPPATH for the configuration path,
  defaults to /etc/slip.

- Adding timeouts for FreeBSD, implemented by counting the usage of the
  slip interface. This means, that we're counting outgoing packets
  instead of the incoming packets under linux.

- access library to gain restricted access (time / user) to each line.
  (this is alpha software!)


Changes from 2.1.0 to 2.1.1
===========================
- To decrease confusion now both slip modes "compress" and "compressed"
 do start cslip.
- If you use ESLIPLOGIN mode (-DESLIPLOGIN), sliplogin will now use
 additional passwords if the loginname matches *SLIP or *SLIP? instead
 of *slip*.
- The rest of the changes does not add new functionality, but was
 necessary to make sliplogin work 'better'.
