Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

perl -h says: 
-d[t][:MOD]           run program under debugger or module Devel::MOD

[download]
But Perl doesn't ship Devel::MOD and it doesn't seem to be on the CPAN.

Re: What is Devel::MOD?

    :MOD is to be read as a placeholder. So if you run

    perl -d:Acme

    [download]

    Perl will go and look for a module Devel::Acme.
