perldoc debug

I don't find which option I should use. Would you please be a little
bit specific?

ITYM perldoc perldebug.

Interestingly enough "perldoc debug" launches the same man page.

Hmmmmm, as I said, works just fine here:

C:\Users\jue>perldoc debug

DESCRIPTION
First of all, have you tried using the -w switch?
:

C:\Documents and Settings\John>perl -v

However, on Ubuntu 8.10:

No documentation found for "debug".


perl -v

So, "blame" ActiveState I guess?

I notice both Strawberry and ActiveState 5.10.1 perldoc's
(v3.15) -- I don't have a 5.10.1 Unix system handy --
apparently apply FWIM (find what I mean) and prepend
'perl' during the search:


c:\strawberry\perl\lib\pods>perldoc -D debug
