NAME
       valtools - introduction to validation tools

DESCRIPTION
       The valtool commands are generally used in shell programming.  These
       commands will prompt for and validate user input.  They generally
       define, among other things, a prompt message, text for help and error
       messages, and a default value (which will be returned if the user
       responds with a carriage return).  All valtool commands begin with a
       ck prefix.

       Visual tool modules are generally linked to the valtool commands.
       They have err (which formats and displays an error message), help
       (which formats and displays a help message), and val (which validates
       a response) prefixes.  For example, the ckpath(1) command has the
       following links: errpath, helppath, and valpath, which are used to
       display an error message, help message, and validate a path.

       The following is a list of the available valtool commands with a
       short description:

                 format.
