       HPUtil::Prompt - Interactive questions

	 use HPUtil::Prompt qw(prompt yes enter);

       The following functions are provided:

       prompt( $question )
       prompt( $question, $default )
       prompt( $question, %opts )
	   This function will ask a question on the terminal and return the
	   answer given.  The return value will always be defined.

	   Options can be passed in as key/value pairs.	 The following options
	   are recognized:


	   The "default" is returned if the user simply press return.  The
	   default value is shown in brackets.	If no default is provided then
	   no brackets are added to the question.

	   If "trim_space" is TRUE, then any leading and trailing space in the
	   anwer is trimmed off and any internal space is collapsed to a sin‐
	   gle space.

	   The "must_match" value is used to validate answers.	It can be
	   either a function, array or regular expression.  If it is a func‐
	   tion, then the function is called with the answer given and should
	   return TRUE if it is to be accepted.	 If it is an array, then the
	   answer must be one of the values in the array.  If it is an regular
	   expression then it must match it.

	   The "no_match_msg" is printed if the given answer does not validate
	   as specified in "must_match".

	   If "use_default" is TRUE, then no answer is read from the terminal
	   and the default is returned (or "" if there is no default).	The
	   "use_default" is by default TRUE if the program is not running on a
	   terminal or if the PERL_MM_USE_DEFAULT environment variable is

	   The "silent" option works like "use_default" but it also prevent
	   the prompt text from being printed.	This forces prompt() to return
	   the default without actually prompting.

       yes( $question )
       yes( $question, $default )
	   Will use the prompt function to ask a question and then return a
	   TRUE value if the answer was "yes" or "y".

	   The $default can either be a string like "yes", "y", "no" or "n",
	   or a boolean value in which case "yes" will be the default if TRUE
	   and "no" otherwise.	If no $default is given it defaults to "no".

	   Ask the use to press some key before the function returns.
