With Pod::Parser, you just do

I run
it, nothing is output.
Oh! I misunderstood, sorry. parse_from_file() does indeed invoke the
parser with the appropriate actions, but what you meant was that
Pod::Parser's "null" parser, when not subclassed, just printed the POD
back out again, so you could use it as a way to extract the POD from a
file. I believe Pod::Simple's "null" parser does nothing at all, so you
get an empty file.
Yes. I think that's an incompatibility.
If I turn on DEBUGing, it's doing a lot. Is there some trivial way to
extract the pod?
So no one thinks there is a trivial way to get this extraction. Would
someone make a suggestion as to the easiest way to do so using modules
that will continue to ship with the Perl 5 core (unlike Pod::Parser)?
No-one answered this, did they?
No
Is it possible to extract the pod by subclassing Pod::Simple, and the
subclass being a null parser that prints out the Pod that it was given?
Nicholas Clark
Yes, but I was hoping there was something that is less work, or already
done, or done for some other purpose, such as Pod::Checker, and I can
re-use the relevant parts.
