* This file contains a command-line user interface for the JPEG compressor.

* It should work on any system with Unix- or MS-DOS-style command lines.

* Two different command line styles are permitted, depending on the

* compile-time switch TWO_FILE_COMMANDLINE:

- * cjpeg [options] inputfile outputfile

- * cjpeg [options] [inputfile]

+ * cjpeg [options] inputfile outputfile

+ * cjpeg [options] [inputfile]

* In the second style, output is always to standard output, which you'd

* normally redirect to a file or pipe to some other program. Input is

* either from a named file or from standard input (typically redirected).

* don't support pipes. Also, you MUST use the first style if your system

* To simplify script writing, the "-outfile" switch is provided. The syntax

- * cjpeg [options] -outfile outputfile inputfile

+ * cjpeg [options] -outfile outputfile inputfile

* works regardless of which command line style is used.
