            Bug ID: 25877
           Summary: Unclear license for example files
           Product: glibc
           Version: 2.31
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: AsDaGo at posteo dot net
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

The manual/examples/README file appears to say that the examples are available
*only* under the GPL. The license notices for the individual files appear to
only allow distribution under the GPL as well. However, since the manual is
licensed under the GFDL, it seems to me that the example files must allow
distribution under the GFDL as well in order to be included in the manual.

So I think this should be clarified by adding a dual-license notice to both the
README and the individual examples allowing distribution under both the GPL and
GFDL.

P.S. Since there is no "documentation" component available, I chose "libc"
instead.

--- Comment #1 from Balint Reczey <balint at balintreczey dot hu> ---
The previous release tarballs did not contain the manual and the examples.

Could you please consider omitting the manual again?

Debian does not recognize GFDL as a DFSG-free license, thus ships the manual
separately.

Are you referring to https://ftp.gnu.org/gnu/glibc/glibc-2.33.tar.xz? It
appears that that contains both the manual and examples. glibc-2.32.tar.xz
contains both as well. Perhaps you meant something else?

I am aware of that. Debian already distributes glibc-doc-reference in the
non-free section, so I don't think anything needs to be changed there.

However, the problem remains that manual/examples/README appears to state that
the examples can only be distributed under the GPL, which seems to contradict
their distribution as part of the manual (which, of course, is under the GFDL).

It may be useful to note that commit d9a17c0 introduced manual/examples/README
and the copyright notices in the example files.

I'm sorry, I stand corrected. Debian repacks the tarball without marking as a
repacked one.
