There is a CRAN package licensed just as "GPL", say, XX, I want to use
in a book.
But I've needed to modify the package to make it do what I need for
expository purposes.
The package author(s) are amenable to my modifications, but probably
unlikely to
incorporate them into the CRAN version any time soon.
Am I allowed, under GPL, to create a new version of the package, say
XX2, in a
public repository such as R-Forge or github? I would, of course,
maintain their
authorship, though perhaps take over the maintainer role. For my
purposes in
the book, I don't necessarily need to release my version to CRAN; just a
public repo
a reader could download from.
