supporting the PNG fi le format in commercial
products. If you use this source code in a product,
acknowledgment is not required but would be
appreciated.
A “png_get_copyright” function is available, for
convenient use in “about” boxes and the like:
printf(“%s”,png_get_copyright(NULL));
Also, the PNG logo (in PNG format, of course) is
supplied in the fi les “pngbar.png” and “pngbar.jpg
(88x31) and “pngnow.png” (98x31).

bison_parser
The distribution terms for Bison-generated parsers
permit using the parsers in nonfree programs.
Before Bison version 2.2, these extra permissions
applied only when Bison was generating LALR(1)
parsers in C. And before Bison version 1.24, Bison-
generated parsers could be used only in programs
that were free software.
The other GNU programming tools, such as
the GNU C compiler, have never had such a
requirement. They could always be used for non
free software. The reason Bison was different was
not due to a special policy decision; it resulted from
applying the usual General Public License to all of
the Bison source code.
The output of the Bison utility the Bison parser fi le
contains a verbatim copy of a sizable piece of Bison,
which is the code for the parser’s implementation.
(The actions from your grammar are inserted into
this implementation at one point, but most of the
rest of the implementation is not changed.) When
we applied the GPL terms to the skeleton code
for the parser’s implementation, the effect was to
restrict the use of Bison output to free software.
We didn’t change the terms because of sympathy
for people who want to make software proprietary.
Software should be free. But we concluded that
limiting Bison’s use to free software was doing little
to encourage people to make other software free.
So we decided to make the practical conditions for
using Bison match the practical conditions for using
the other GNU tools.
This exception applies when Bison is generating
code for a parser. You can tell whether the exception
applies to a Bison output fi le by inspecting the fi le
for text beginning with ¨As a special exception....
The text spells out the exact terms of the
exception.
