[Arg-parser-bug] Arg_parser 1.10 released

[Antonio Diaz Diaz]

I am pleased to announce the release of Arg_parser 1.10.

Arg_parser is an argument parser that follows POSIX and GNU conventions 
for command line arguments. There exist C++ and C versions of 
Arg_parser. The C++ version is implemented as a C++ class, while the C 
version is implemented as a single struct plus associated functions. 
Both are simpler, easier to use, and safer that 'getopt_long'.

The C++ version of Arg_parser can also parse options from configuration 
files.

The homepage is at http://www.nongnu.org/arg-parser/arg_parser.html

The sources can be downloaded from
http://download.savannah.gnu.org/releases/arg-parser/

The sha1sum is:
1bcb4b55b893f56531c9dab8ee0fadd92240b33e  arg_parser-1.10.tar.lz

This release is also GPG signed. You can download the signature by 
appending ".sig" to the URL.

Changes in version 1.10:

  * The license has been changed to "GPL version 2 or later with link 
exception".

                                 -----

Rationale for the license change.

I have recently been shocked to know that it is apparently not legal to 
use Arg_parser in GPLv2 programs. Linking those programs with Arg_parser 
violates the GPLv2. But linking proprietary programs with Arg_parser is 
fine and legal!

This problem is not caused by any fault in Arg_parser's link exception; 
the LGPLv3 has the same problem. See for example 
http://nmav.gnutls.org/2013/03/the-perils-of-lgplv3.html

Of course it was never my intention to prevent GPLv2 programs from using 
Arg_parser. I apologize for any inconveniences my oversight may have 
caused to distributions, GPLv2 software projects, and users in general.
