Hum.. I think so.

I tested config variables 'help.format' and 'man.viewer', again.
Selecting which manual page viewer can be done by both
this config variables.

So IMHO I think even if 'help.format' is removed,
it hasn't problem because this functionality is duplicated.
And I think it seems to be tidy that the whole 'help' section
is removed or just don't document it on perf-config doc.

Would I keep working on perf-config patchkit excluding 'help' section ?


Thanks,
