I see I have _two_ versions of system-config-printer
on my laptop, in /usr/bin (which takes priority) and /usr/sbin :
-----------------------------------
[tim@elizabeth ~]$ ls -ls `which system-config-printer`
0 lrwxrwxrwx 1 root root 13 Aug 23 13:10 /usr/bin/system-config-printer ->
consolehelper
[tim@elizabeth ~]$ ls -ls /usr/sbin/system-config-printer
0 lrwxrwxrwx 1 root root 9 Aug 23 13:10 /usr/sbin/system-config-printer ->
printconf
-----------------------------------
Both versions are supplied by the same (recent) system-config-printer rpm.

Incidentally, I wasn't suggesting that programs written in Python or Perl
are necessarily more readable than programs in C -
I actually believe the opposite -
but if a program is written in Python or Perl
it is easier to trace what is happening,
eg by inserting temporary print commands.
