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 开发者_StackOverflowtex.stackexchange.com here, however there is not much traffic on that site.

Just found the pdfcomment package, which is working out very nicely: http://pdfcomment.berlios.de/

allows one to add sticky-note type comments throughout the resulting pdf file.

simply set a global option for pdfcomment in your preable to either 'draft' or 'final' to make the comments show up or not.

I'm finding this extremely helpful for reminding myself where i need to add a reference/figure etc. However, I'm using Mac OS & pdftex (default for TexLive 2009), which has excellent support for PDF comments (in both Safari & Preview.app). Not really sure how well supported this is on Linux/Windows type OS's.

Example preamble:

\usepackage{pdfcomment} \pdfcommentsetup{draft} % set to 'final' to prevent all comments from showing up \pdfcommentsetup{color={1.0 1.0 0.0}, open=true}

Example usage:

... diffuse into the substrate in every direction - ie. radially.\pdfcomment{Need reference for this type of model.} ...

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.
