** PROGRAM:   curlfish - a program just about as simple as they come.         ** 
** AUTHOR:    Matt Livingston (blubrick@gmail.com)                            **
** PURPOSE:   Notifies the user that their script has CRLF line endings       **
** DATE:      05 October, 2018  (Originally sometime in 2001, I think)        **
**                                                                            **
** The name comes from an abbreviation of, then an expansion of, "CRLF shell" **
** (CRLF SHELL -> crlfsh - > curlfish)                                        **
