The 1.1 series are the current development branch of GnuPG.
DO NOT USE IN A PRODUCTION ENVIRONMENT!
THERE MIGHT EVEN BE SECURITY PROBLEMS!
The source may change quite often and may have serious
problems; it may even not compile on some machines.
It will probably need GCC and GLIBC to build due to
some debugging code. Please don't complain if it does not
work on other machines. We will make it work again later.
Use GnuPG from the stable 1.0.x series for real work.
If you are looking for the CVS from the stable tree, use
cvs -z3 -d :pserver:anoncvs@cvs.gnupg.org:/cvs/gnupg co -r STABLE-BRANCH-1-0 gnupg

jnlib - this is a collection of utility function which are
too small to put into a library.
libjnlib-config.h should be be modified for each project
to make these functions fit into the software. Mainly these
are memory functions in case you need another allocaort (like gcrypt).

*
* @Description
* This is my replacement for getopt(). See the example for a typical usage.
* Global flags are:
* Bit 0 : Do not remove options form argv
* Bit 1 : Do not stop at last option but return other args
* with r_opt set to -1.
* Bit 2 : Assume options and real args are mixed.
* Bit 3 : Do not use -- to stop option processing.
* Bit 4 : Do not skip the first arg.
* Bit 5 : allow usage of long option with only one dash
* Bit 6 : ignore --version
* all other bits must be set to zero, this value is modified by the
* function, so assume this is write only.
* Local flags (for each option):
* Bit 2-0 : 0 = does not take an argument
* 1 = takes int argument
* 2 = takes string argument
* 3 = takes long argument
* 4 = takes ulong argument
* Bit 3 : argument is optional (r_type will the be set to 0)
* Bit 4 : allow 0x etc. prefixed values.
* Bit 7 : this is a command and not an option
* You stop the option processing by setting opts to NULL, the function will
* then return 0.
* @Return Value
* Returns the args.r_opt or 0 if ready
* r_opt may be -2/-7 to indicate an unknown option/command.
* @See Also
* ArgExpand
* @Notes
* You do not need to process the options 'h', '--help' or '--version'
* because this function includes standard help processing; but if you
* specify '-h', '--help' or '--version' you have to do it yourself.
* The option '--' stops argument processing; if bit 1 is set the function
* continues to return normal arguments.
* To process float args or unsigned args you must use a string args and do
* the conversion yourself.
* @Example
*
* ARGPARSE_OPTS opts[] = {
* { 'v', "verbose", 0 },
* { 'd', "debug", 0 },
* { 'o', "output", 2 },
* { 'c', "cross-ref", 2|8 },
* { 'm', "my-option", 1|8 },
* { 500, "have-no-short-option-for-this-long-option", 0 },
* {0} };
* ARGPARSE_ARGS pargs = { &argc, &argv, 0 }
*
* while( ArgParse( &pargs, &opts) ) {
* switch( pargs.r_opt ) {
* case 'v': opt.verbose++; break;
