Is this copyright information sufficient for distributing theme files?

Question

I need to distribute theme files to several colleagues, and the templates I'm working off of all have this header:

Copyright year by name <email>

This file may be distributed and/or modified

1. under the LaTeX Project Public License and/or
2. under the GNU Public License.

See the file doc/licenses/LICENSE for more details.

I read through the Beamer manual's copyright section, am I interpreting it correctly that this is all I need to include in the file?

EDIT:

Since the theme files don't have to be placed in the LaTeX distribution location (they'll also work in the compiling directory) I wanted to clear that last line up some. I was going to specify a more specific path, but it turns out I can't find the correct doc/licenses/* files either. Looking at LICENSE which I found on what looks like CTAN, none of the other files are there. I can't find manifest-code.txt, I can't find manifest-documentation.txt, and I can't find the plain text version of the license. I can't even find that directory in either of the LaTeX distributions I have access to. Since I know the license is in the Beamer manual, I'll just direct to that with

See the Section 'Licenses and Copyright' in the Beamer manual for more details.

Answer 1

personally, i would be happy with that, except i don't know where doc/licenses/LICENSE would live -- it had better be something relative to where the licence statement lives. subject to that, it would pass the ctan catalogue checks.

note that the ctan catalogue only ever lists a single licence. which one gets chosen to appear in the catalogue page for the package is up to the ctan team member who gets to write the catalogue entry.
