extract text from tex, remove latex tags

Question

I have some .tex files from which I want to receive the plain text without any latex tags such as \section{...} or \newpage.
Does anybody have any idea on how to achieve this? I also have the .pdf file but when I just copy the code from there, some words get concatenated which is real bad.
Is there any tool you know?

Please see the OpenDetex GitHub page for the latest version of OpenDetex. It is a more modern, derivative version of my original DeTeX.

My legacy DeTeX home page is available here.

If you just want the legacy detex-2.8.tar source, you can get it here.
