   * Fixed many bugs

Version 2.22.5

   * correctly wraps and preprocess the specified usage string
   * handle escaped newline chars in the .ggo file correctly
   * initialize enum variables with a generated null value (makes
     the parser compilable in C++)

Version 2.22.4

   * switched to git repository
   * removed other gcc compilation warnings on generated files

Version 2.22.3

   * enum option values can contain + and - (thanks to Papp Gyozo).
   * fixed compilation problems due to macro FIX_UNUSED which was not
   in the right place (thanks to Matthew Junker)
   * --header-output-dir and --src_output-dir to store cmdline.h 
   separately from cmdline.c (thanks to Yegor Yefremov)

   * generated functions use prototypes with char ** instead of
	char *const *

Version 2.22.2

   * removed further compilation warnings for generated files
   * fixed a compilation problems for files generated with --include-getopt
     with some versions of stdlib.h
   * removed dependency from flex library (that generated problems in
     compilation in open solaris)

Version 2.22.1

   * removed compilation warnings for generated files

Version 2.22

   * avoid test suite if crosscompiling
   * generated code is averagely less verbose
   * generate a function to save the command line options into an open stream
     (thanks to Papp Gyozo).
   * given fields are unsigned also for non multiple options
   * removed compilation warnings for generated code when using
     -Wstrict-prototypes (thanks to Andre Noll)
   * added print_errors parameters to pass to generated parser function to
     suppress getopt_long message printing (thanks to J. David Bryan)
   * if h is specified as a short option, then --help is still automatically
     generated, the same holds for --version and v (thanks to J. David Bryan)
   * initializing of the structure for parser function parameters
     was changed in order to initialize the fields to their default values
     (instead of 0)
   * list of acceptable values for options can be have a type different from
     string and can have type enum (that will generate a C enum)
     (as suggested by Gyozo Papp)
   * usage string is printed only if not empty (as suggested by Gyozo Papp)
   * in case of hidden options, the generated help string array reuses the 
     strings of the full help array (as suggested by Gyozo Papp)

     of additional text before and after an option and also groups
   * for an option one can specify the "details" which will be printed in
     case --detailed-help is specified
   * mode options: if an option of a mode is given no option of another
     mode can be specified (mutually exclusive groups of options)
   * can use ? as short option
   * --no-help, --no-version: don't add --help and --version automatically
     (the user can specify those options manually)

   * usage string can be specified (instead of being generated automatically).
   * description string can be specified that will be printed after the
     usage string.

   * when invoking getopt_long, discard any pointers to previously
     scanned command lines (thanks to Andre Noll)
   * fixed a bug in generation of help strings that might cause
     a seg fault (reported by Paul Biggar)

Version 2.15

   * option parts can be specified in any order
   * options can be hidden (not shown in the --help output)
   * an option can depend on another option
   * when converting a numeric string check for the result

     (with help from Gyozo Papp)
   * wrapping is applied to all description strings (with help from Gyozo Papp)
   * better check for "strings" well-formedness in configuration files
     (with help from Gyozo Papp)

Version 2.12.1

   * the generated source include config.h before any other header:
     otherwise some problems may come up in some circumstances
     (reported by Heinz Salzmann)
   * options can have optional arguments (as suggested by
     Guillaume Chazarain)

     allocated for the option arguments by the parser
     and memory leaks in the generated files are removed
     (thanks to Michael Hagemann)
   * an _init function is generated that is called instead of clear_args
     and a initialize parameter has to be passed to the config file parser
     stating whether the args_info struct has to be initialized
     (Richard Zidlicky reported problems if the config file parser is
     called before the standard command line parser)
   * a second parser function is generated that allows to specify the
     override and initialize parameters that should be used together with
     the config file parser.  You can also specify whether the
     check for required option must be performed.
   * --arg-struct-name option for specifying the name of the generated
     struct for args info (suggested by Richard Zidlicky)
   * --unamed-opts can be given an optional argument
     describing the additional arguments without names, default is still
     FILES (as suggested by Simon Josefsson)

     extensions of generated files.

   * fixed a small bug in the generated config file parser
     (reported by Karsten Reincke)
   * default values work for multiple options
     (reported by Christian Richter)
   * multiple options can be specified also without a short form
   * output of --help is wrapped (thanks to Michael Hagemann)

     (e.g., FILENAME instead of STRING) (thanks to Michael Hagemann)
   * added sections for options

     standard library (thanks to Bert Deknuydt)
   * handle spaces in group names (reported by Matthew K. Junker)
   * package and version defined in a .ggo file have the precedence
     over PACKAGE and VERSION (reported by Kat Manton)

   * correctly cast results of malloc in generated code
   * in the generated parser the generated version of strdup is
     always used (to improve portability)
