%description
  TUN/TAP provides packet reception and transmission for user space programs. 
  It can be viewed as a simple Point-to-Point or Ethernet device, which 
  instead of receiving packets from a physical media, receives them from 
  user space program and instead of sending packets via physical media 
  writes them to the user space program.

# the alteration to the install section is intended to supply ONLY the
# files required for each platform.  Given the magic with the tun
# module checking to see if it needs to be built, some magic with
# %files -f is required.

#okay, you NEED this, Max.  It is for repeat builds.  Stop deleting it.

* Thu Dec 20 2001 Bishop Clark (LC957) <[e-mail]>         1.1-6
- edit spec file to account for continuing COL/rpm306 builds like on
  20011112
* Mon Dec 03 2001 Bishop Clark (LC957) <[e-mail]>         1.1-5
- semi-intelligent tun module addition/removal, with a checker
  warning.
* Tue Nov 20 2001 Bishop Clark (LC957) <[e-mail]>         1.1-4
- tun/tap devices on kernel 2.2 now 0-9 from 0-3.  Cleaned up creation
  routine.
* Fri Nov 16 2001 Bishop Clark (LC957) <[e-mail]>         1.1-3
- the kernel=%(uname -r)Requires: line doesn't work.  Removing for
  now.
- change to buildshell part to on-the-fly do bash2.  RH62 hated it
  before.
* Mon Nov 12 2001 Bishop Clark (LC957) <[e-mail]>         1.1-2
- Added minor change to support COL 31 builds
- more commenting, to explain weird stuff.
* Wed Oct 31 2001 Bishop Clark (LC957) <[e-mail]>         1.1-1lc1
- remove directory so repeat builds succeed (3rd time)
- fixed a schroedinger's tun problem with trying to install or package
  nonexistent files
- only package files required for the target (no 2.4 devs on 2.2)
- more accurately tracks the kernel version
