+/**
+ * Zend_Console_Getopt is a class to parse options for command-line
+ * applications.
+ *
+ * Terminology:
+ * Argument: an element of the argv array.  This may be part of an option,
+ *   or it may be a non-option command-line argument.
+ * Flag: the letter or word set off by a '-' or '--'.  Example: in '--output filename',
+ *   '--output' is the flag.
+ * Parameter: the additional argument that is associated with the option.
+ *   Example: in '--output filename', the 'filename' is the parameter.
+ * Option: the combination of a flag and its parameter, if any.
+ *   Example: in '--output filename', the whole thing is the option.
+ *
+ * The following features are supported:
+ *
+ * - Short flags like '-a'.  Short flags are preceded by a single
+ *   dash.  Short flags may be clustered e.g. '-abc', which is the
+ *   same as '-a' '-b' '-c'.
+ * - Long flags like '--verbose'.  Long flags are preceded by a
+ *   double dash.  Long flags may not be clustered.
+ * - Options may have a parameter, e.g. '--output filename'.
+ * - Parameters for long flags may also be set off with an equals sign,
+ *   e.g. '--output=filename'.
+ * - Parameters for long flags may be checked as string, word, or integer.
+ * - Automatic generation of a helpful usage message.
+ * - Signal end of options with '--'; subsequent arguments are treated
+ *   as non-option arguments, even if they begin with '-'.
+ * - Raise exception Zend_Console_Getopt_Exception in several cases
+ *   when invalid flags or parameters are given.  Usage message is
+ *   returned in the exception object.
+ *
+ * The format for specifying options uses a PHP associative array.
+ * The key is has the format of a list of pipe-separated flag names,
+ * followed by an optional '=' to indicate a required parameter or
+ * '-' to indicate an optional parameter.  Following that, the type
+ * of parameter may be specified as 's' for string, 'w' for word,
+ * or 'i' for integer.
+ *
+ * Examples:
+ * - 'user|username|u=s'  this means '--user' or '--username' or '-u'
+ *   are synonyms, and the option requires a string parameter.
+ * - 'p=i'  this means '-p' requires an integer parameter.  No synonyms.
+ * - 'verbose|v-i'  this means '--verbose' or '-v' are synonyms, and
+ *   they take an optional integer parameter.
+ * - 'help|h'  this means '--help' or '-h' are synonyms, and
+ *   they take no parameter.
+ *
+ * The values in the associative array are strings that are used as
+ * brief descriptions of the options when printing a usage message.
+ *
+ * The simpler format for specifying options used by PHP's getopt()
+ * function is also supported.  This is similar to GNU getopt and shell
+ * getopt format.
+ *
+ * Example:  'abc:' means options '-a', '-b', and '-c'
+ * are legal, and the latter requires a string parameter.

+ * @version    Release: @package_version@
+ * @since      Class available since Release 0.6.0
+ *
+ * @todo  Handle params with multiple values, e.g. --colors=red,green,blue
+ *        Set value of parameter to the array of values.  Allow user to specify
+ *        the separator with Zend_Console_Getopt::CONFIG_PARAMETER_SEPARATOR.
+ *        If this config value is null or empty string, do not split values
+ *        into arrays.  Default separator is comma (',').
+ *
+ * @todo  Handle params with multiple values specified with separate options
+ *        e.g. --colors red --colors green --colors blue should give one
+ *        option with an array(red, green, blue).
+ *        Enable with Zend_Console_Getopt::CONFIG_CUMULATIVE_PARAMETERS.
+ *        Default is that subsequent options overwrite the parameter value.
+ *
+ * @todo  Handle flags occurring multiple times, e.g. -v -v -v
+ *        Set value of the option's parameter to the integer count of instances
+ *        instead of a boolean.
+ *        Enable with Zend_Console_Getopt::CONFIG_CUMULATIVE_FLAGS.
+ *        Default is that the value is simply boolean true regardless of
+ *        how many instances of the flag appear.
+ *
+ * @todo  Handle flags that implicitly print usage message, e.g. --help
+ *
+ * @todo  Handle freeform options, e.g. --set-variable
+ *        Enable with Zend_Console_Getopt::CONFIG_FREEFORM_FLAGS
+ *        All flag-like syntax is recognized, no flag generates an exception.
+ *
+ * @todo  Handle numeric options, e.g. -1, -2, -3, -1000
+ *        Enable with Zend_Console_Getopt::CONFIG_NUMERIC_FLAGS
+ *        The rule must specify a named flag and the '#' symbol as the
+ *        parameter type. e.g.,  'lines=#'
+ *
+ * @todo  Enable user to specify header and footer content in the help message.
+ *
+ * @todo  Feature request to handle option interdependencies.
+ *        e.g. if -b is specified, -a must be specified or else the
+ *        usage is invalid.
+ *
+ * @todo  Feature request to implement callbacks.
+ *        e.g. if -a is specified, run function 'handleOptionA'().
