// Strips the <CR> character from DOS files, which
// use <CR><LF> at the end of each line, to make the source files compatible
// with the <LF> terminated lines of Unix/Linux/OS X. This utility takes a
// stream of characters from the standard input and produces an output
// stream of characters to the standard output. You should run DOS files
// through this utility or its equivalent before using asem8, as the Pep/8
// assembler assumes <LF> terminated lines. It also appends a <LF> character
// at the end of the file to assure that the last line terminates with a
// newline.
