#
#	The cmdline::getopt works in a fashion like the standard

#	pointer to an array or args this command will process the
#	first argument and return info on how to proceed.
#
# Arguments:
#	argvVar		Name of the argv list that you
#			want to process.  If options are found the
#			arg list is modified and the processed arguments
#			are removed from the start of the list.
#	optstring	A list of command options that the application
#			will accept.  If the option ends in ".arg" the
#			getopt routine will use the next argument as 
#			an argument to the option.  Otherwise the option	
#			is a boolean that is set to 1 if present.
#	optVar		The variable pointed to by optVar
#			contains the option that was found (without the
#			leading '-' and without the .arg extension).
#	valVar		Upon success, the variable pointed to by valVar
#			contains the value for the specified option.
#			This value comes from the command line for .arg
#			options, otherwise the value is 1.
#			If getopt fails, the valVar is filled with an
#			error message.
#
# Results:
# 	The getopt function returns 1 if an option was found, 0 if no more
# 	options were found, and -1 if an error occurred.

# ::cmdline::typedGetopt --
#
#	The cmdline::typedGetopt works in a fashion like the standard
#	C based getopt function.  Given an option string and a
#	pointer to a list of args this command will process the
#	first argument and return info on how to proceed. In addition,
#	you may specify a type for the argument to each option.
#
# Arguments:
#	argvVar		Name of the argv list that you want to process.
#			If options are found, the arg list is modified
#			and the processed arguments are removed from the
#			start of the list.
#
#	optstring	A list of command options that the application
#			will accept.  If the option ends in ".xxx", where
#			xxx is any valid character class to the tcl
#			command "string is", then typedGetopt routine will
#			use the next argument as a typed argument to the
#			option. The argument must match the specified
#			character classes (e.g. integer, double, boolean,
#			xdigit, etc.). Alternatively, you may specify
#			".arg" for an untyped argument.
#
#	optVar		Upon success, the variable pointed to by optVar
#			contains the option that was found (without the
#			leading '-' and without the .xxx extension).  If
#			typedGetopt fails the variable is set to the empty
#			string. SOMETIMES! Different for each -value!
#
#	argVar		Upon success, the variable pointed to by argVar
#			contains the argument for the specified option.
#			If typedGetopt fails, the variable is filled with
#			an error message.
#
# Argument type syntax:
#	Option that takes no argument.
#		foo
#
#	Option that takes a typeless argument.
#		foo.arg
#
#	Option that takes a typed argument. Allowable types are all
#	valid character classes to the tcl command "string is".
#	Currently must be one of alnum, alpha, ascii, control,
#	boolean, digit, double, false, graph, integer, lower, print,
#	punct, space, true, upper, wordchar, or xdigit.
#		foo.double
#
#	Option that takes an argument from a list.
#		foo.(bar|blat)
#
# Argument quantifier syntax:
#	Option that takes an optional argument.
#		foo.arg?
#
#	Option that takes a list of arguments terminated by "--".
#		foo.arg+
#
#	Option that takes an optional list of arguments terminated by "--".
#		foo.arg*
#
#	Argument quantifiers work on all argument types, so, for
#	example, the following is a valid option specification.
#		foo.(bar|blat|blah)?
#
# Argument syntax miscellany:
#	Options may be specified on the command line using a unique,
#	shortened version of the option name. Given that program foo
#	has an option list of {bar.alpha blah.arg blat.double},
#	"foo -b fob" returns an error, but "foo -ba fob"
#	successfully returns {bar fob}
#
# Results:
#	The typedGetopt function returns one of the following:
#	 1	a valid option was found
#	 0	no more options found to process
#	-1	invalid option
#	-2	missing argument to a valid option
#	-3	argument to a valid option does not match type
#
# Known Bugs:
#	When using options which include special glob characters,
#	you must use the exact option. Abbreviating it can cause
#	an error in the "cmdline::prefixSearch" procedure.

# ::cmdline::typedGetoptions --
#
#	Process a set of command line options, filling in defaults
#	for those not specified. This also generates an error message
#	that lists the allowed options if an incorrect option is
#	specified.
#
# Arguments:
#	arglistVar	The name of the argument list, typically argv
#	optlist		A list-of-lists where each element specifies an option
#			in the form:
#
#				option default comment
#
#			Options formatting is as described for the optstring
#			argument of typedGetopt. Default is for optionally
#			specifying a default value. Comment is for optionally
#			specifying a comment for the usage display. The
#			options "--", "-help", and "-?" are automatically included
#			in optlist.
#
# Argument syntax miscellany:
#	Options formatting and syntax is as described in typedGetopt.
#	There are two additional suffixes that may be applied when
#	passing options to typedGetoptions.
#
#	You may add ".multi" as a suffix to any option. For options
#	that take an argument, this means that the option may be used
#	more than once on the command line and that each additional
#	argument will be appended to a list, which is then returned
#	to the application.
#		foo.double.multi
#
#	If a non-argument option is specified as ".multi", it is
#	toggled on and off for each time it is used on the command
#	line.
#		foo.multi
#
#	If an option specification does not contain the ".multi"
#	suffix, it is not an error to use an option more than once.
#	In this case, the behavior for options with arguments is that
#	the last argument is the one that will be returned. For
#	options that do not take arguments, using them more than once
#	has no additional effect.
#
#	Options may also be hidden from the usage display by
#	appending the suffix ".secret" to any option specification.
#	Please note that the ".secret" suffix must be the last suffix,
#	after any argument type specification and ".multi" suffix.
#		foo.xdigit.multi.secret
#
# Results
#	Name value pairs suitable for using with array set.
