MS-DOS/Windows editors end all lines of text with <CR><LF> pairs, while
UNIX text uses only single <LF> characters (a.k.a. <NL> or "new line").
If you edit a UNIX script on a DOS system, the embedded <CR> characters
will prevent it from running correctly when it's copied over to a UNIX
system using an exact binary transfer. When in the default ASCII
transfer mode, the ftp command line client will insert or strip carriage
return characters associated with line feeds, depending on which
direction the file is being transferred.
An equivalent way to make sure there are no embedded <CR> characters in
a UNIX script is to use the 'dos2unix' utility on it after receipt.
