The problem

The --man code example provided in the Rendering Pod to Text section has some issues:

• It will only render Pod in the file being executed by Raku. This is
  problematic if you intend to distribute the program via Zef, as $*PROGRAM will
  not point to the original script but a wrapper without the Pod instead.
• Performance issues from invoking Raku.

Solution provided

• Print the output of pod2text $=pod using Pod::To::Text directly. This way
  we do not have to rely on $*PROGRAM pointing to our script file. It's also
  faster than re-invoking Raku.
