What's with the excessive comments?

You are setting yourself up to call two Perl programs in a pipe, why
bother? Better to take like components, develop a library and then call
the interfaces directly.

Not terribly informative, let's hope that isn't where the problem is...

One of the reasons why you may not get much assistance is that your
current code looks like a time sink because your functions are not
encapsulated. In general subroutines should take arguments and return
values...
> $code = $File::Find::name;
> $name = $web_dir.'/'.$_;
Where did these two come from? I assume your call to File::Find has
been tested...

perldoc -f system
System isn't likely returning what you think it is. Speaking of which,
it might help if you told us what you are expecting it to return since
we know nothing about the sequence of programs you are using.

Which leads me to believe outline2html is expecting file arguments and
doesn't recognize -p and -t as switches.

Depends on outline2html.pl which I (we) are not familar with.

Backticks, qx(), but then it is usually discouraged, why call a program
written in the same language by shelling out?
