--# shFlags -- Advanced command-line flag library for Unix shell scripts.
--# http://code.google.com/p/shflags/
--#
--# Author: kate.ward@forestent.com (Kate Ward)
--#
--# This module implements something like the google-gflags library available
--# from http://code.google.com/p/google-gflags/.
--#
--# FLAG TYPES: This is a list of the DEFINE_*'s that you can do. All flags take
--# a name, default value, help-string, and optional 'short' name (one-letter
--# name). Some flags have other arguments, which are described with the flag.
--#
--# DEFINE_string: takes any input, and intreprets it as a string.
--#
--# DEFINE_boolean: typically does not take any argument: say --myflag to set
--# FLAGS_myflag to true, or --nomyflag to set FLAGS_myflag to false.
--# Alternately, you can say
--# --myflag=true or --myflag=t or --myflag=0 or
--# --myflag=false or --myflag=f or --myflag=1
--# Passing an option has the same affect as passing the option once.
--#
--# DEFINE_float: takes an input and intreprets it as a floating point number. As
--# shell does not support floats per-se, the input is merely validated as
--# being a valid floating point value.
--#
--# DEFINE_integer: takes an input and intreprets it as an integer.
--#
--# SPECIAL FLAGS: There are a few flags that have special meaning:
--# --help (or -?) prints a list of all the flags in a human-readable fashion
--# --flagfile=foo read flags from foo. (not implemented yet)
--# -- as in getopt(), terminates flag-processing
--#
--# EXAMPLE USAGE:
--#
--# -- begin hello.sh --
--# #! /bin/sh
--# . ./shflags
--# DEFINE_string name 'world' "somebody's name" n
--# FLAGS "$@" || exit $?
--# eval set -- "${FLAGS_ARGV}"
--# echo "Hello, ${FLAGS_name}."
--# -- end hello.sh --
--#
--# $ ./hello.sh -n Kate
--# Hello, Kate.
--#
--# NOTE: Not all systems include a getopt version that supports long flags. On
--# these systems, only short flags are recognized.
