First thing I did after installing man pages was to create the `cat' 
dirs. ;)

I've just tried `man ruptime', where /usr/share/man/cat1/ruptime.1.gz
exists on both machines:
-rw-rw-r--  1 man  bin  604 Jan 10 18:43 /usr/share/man/cat1/ruptime.1.gz
-rw-rw-r--    1 man           614 Jan 10 13:07 /usr/share/man/cat1/ruptime.1.gz
(Hmmm, time zone is screwed.)

== 2.0 == 2.17 real         0.56 user         0.64 sys                      
== 1.x == 1.07 real         0.13 user         0.20 sys       


For `time zcat /usr/share/man/cat1/ruptime.1.gz':
== 2.0 == 0.16 real         0.05 user         0.13 sys
== 1.x == 0.05 real         0.01 user         0.03 sys       


What about `time cat /etc/sendmail.cf', with identical files?
== 2.0 ==  0.71 real         0.02 user         0.36 sys       
== 1.x ==  0.17 real         0.00 user         0.10 sys        


Can someone running 1.x and 2.0 on almost similar h/w take a moment
and try these, please? 

Thanx.
