jwe,
If you try 'help bzip2' you'll see a bunch of cruft at the end of the
docstring which is the standard GPL file preamble. The issue is in
libinterp/module.mk:
module.mk: ( $(PERL) $(srcdir)/libinterp/gendoc.pl "$(srcdir)"
$(LIBINTERP_DEFUN_FILES); cat $(srcdir)/libinterp/op-kw-docs ) >
libinterp/DOCSTRINGS-t && \
Using 'cat' adds the entire file to DOCSTRINGS including the GPL preamble.
There is a note in op-kw-docs:
## FIXME: the information in this file is currently duplicated in help.cc.
Maybe an entirely different solution is desired given the FIXME note. At
any rate, I thought I'd let you two know since you were working on this.
