Latex tag for making a comment appear or disappear in pdf?

Is it possible to tag sections of your .tex file so that you can make text appear or not?

I have a long document and would like to be able to comment a certain section in each chapter, and produce two different pdfs, one with the comments, and one without.

I read here about the \begin{comment} tag in the verbatim package. Is it possible to make this appear if I redefined the comment tag? How is this done?

Thank you.

On suggestion, included the question to tex.stackexchange.com here, however there is not much traffic on that site.

    Yes, this is indeed possible, and it’s very simple, too: just redefine the comment environment as follows:

    \renewenvironment{comment}{}{}

    This will cause the comment text to be included as normal text.
