In this question about adding visual style and pizzaz one person gave an answer with a link to a package (grid.sty) whose documentation contains a style that suits me a lot. I would like to use it in a document I'm typesetting but I'm left wondering if I should leave the copyright as is or if I could remove it or change it to a copyright notice of my own making. What is the consensus in the TeX community? Has this issue cropped up for anyone else before?
The packages I'm using for incorporating this style into my memoir document are
I'm not using elsarticle.sty
The license of the packages is the LPPL 1.2. I read the document and it doesn't seem to mention that the copyright must be visible in the generated document. However, to change the copyright information one would have to change the package rvdtx.sty, which would imply making a Derived Work. Can I and should I post these alteration online? Should I ask the copyright holder?
An image of how it looks (the copyright notice by Elsevier and River Valley is at the bottom:) .
If this issue hasn't come up before and it's absolutely necessary to contact a lawyer about this, I think I just won't use the style.
EDIT: to sum up and remove ambiguities in my question:
- The package rvdtx.sty includes a copyright notice for Elsevier in every footer. This is not configurable with package arguments
- I would like to change or eliminate this, thus I would have to modify the package
- Is this legal according to the LPPL (the license of the package)? What would I have to do to ensure the legality of my actions?
