AutoOpts

Equivalenced options may now be preset with
configuration files and environment variables.
Placing command line options in a ${PROGNAME}
environment variable is now supported.
"autoopts-config" will now include the "-R"
option. "autoopts.pc" is produced for use by
pkgconfig. The docs on option argument usage were
improved.

The listing of enumerated option arguments is now more
concise. Options may be handled twice: once during the
immediate phase and during "normal" processing. The
"${PROGNAME}" environment variable can be processed
tokenizing and processing it as a list of command line
options. There is a new main procedure type, each-or-stdin,
which will fopen() each command line operand and pass the
FILE* pointer to the callout procedure. If there are no
operands, then stdin is passed.

This release is internationalized, requiring the tear-off redistributable sources to be built differently. It also contains a reworked main() procedure generator.

This release produces I18N-compliant option processing code. If client programs localize the distributed file "usage-txt.h" and their generated .c file, and then compile with "ENABLE_NLS'', then all of the error messages and usage text produced by AutoOpts will be translated. Additionally, there is a new template, "getopt.tpl", that will produce C code that utilizes "getopt_long(3GNU)" to parse the command line options. Many features are disabled, but it removes the libopts dependency.

A "set membership" option argument type has been added. Command line options can be used to set and clear membership bit flags and easy-to-use macros can be used in your code to test membership. A few obscure bugs were also fixed.
