Release Notes: Strings can spawn more than one line and contain escaped ". The usage string can be specified (instead of being generated automatically). A description string can be specified that will be printed after the usage string. Automatically created usage strings are wrapped. With --long-help, the optional options are correctly printed between square brackets. The option --show-required was added in order to explicitly print in the help output whether an option is mandatory. Configuration files can include other configuration files. The option --no-handle-help also handles --full-help.
Release Notes: A compilation problem in Mac OS X has been fixed. The versiontext directive has been added. The commandline option --strict-hidden has been added. Many bugs have been fixed.
Release Notes: Wrapping and preprocessing of strings is correctly handled. Enum variables are initialized with a generated null value (this makes the parser compilable in C++). Warnings in the generated parser when only flags are used are now removed.
Release Notes: This release has switched to using a git repository. Other gcc compilation warnings on generated files were removed.
Release Notes: Enum option values can now contain + and -. Compilation problems due to the FIX_UNUSED macro not being in the right place were fixed. --header-output-dir and --src_output-dir command line options were added to store cmdline.h separately from cmdline.c. Generated functions use prototypes with char ** instead of char *const *.
Release Notes: Further compilation warnings for generated files were removed. A compilation problem for files generated with --include-getopt with some versions of stdlib.h was fixed. The dependency on the flex library (which generated problems in compilation in Open Solaris) was removed. PACKAGE_NAME, if defined, is used for printing help and version. The configure option --docdir is now used, if specified for installing documentation.
