+* Copyright (C) 1991-1998, Thomas G. Lane.

+* This file is part of the Independent JPEG Group's software.
+* For conditions of distribution and use, see the accompanying README file.
+*
+* 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]
+* 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).
+* The second style is convenient on Unix but is unhelpful on systems that
+* don't support pipes.  Also, you MUST use the first style if your system
+* doesn't do binary I/O to stdin/stdout.
+* To simplify script writing, the "-outfile" switch is provided.  The syntax
+*	cjpeg [options]  -outfile outputfile  inputfile
+* works regardless of which command line style is used.

+* This routine determines what format the input file is,
+* and selects the appropriate input-reading module.
+*
+* To determine which family of input formats the file belongs to,
+* we may look only at the first byte of the file, since C does not
+* guarantee that more than one character can be pushed back with ungetc.
+* Looking at additional bytes would require one of these approaches:
+*     1) assume we can fseek() the input file (fails for piped input);
+*     2) assume we can push back more than one character (works in
+*        some C implementations, but unportable);
+*     3) provide our own buffering (breaks input readers that want to use
+*        stdio directly, such as the RLE library);
+* or  4) don't put back the data, and modify the input_init methods to assume
+*        they start reading after the start of file (also breaks RLE library).
+* #1 is attractive for MS-DOS but is untenable on Unix.
+*
+* The most portable solution for file types that can't be identified by their
+* first byte is to make the user tell us what they are.  This is also the
+* only approach for "raw" file types that contain only arbitrary values.
+* We presently apply this method for Targa files.  Most of the time Targa
+* files start with 0x00, so we recognize that case.  Potentially, however,
+* a Targa file could start with any byte value (byte 0 is the length of the
+* seldom-used ID field), so we provide a switch to force Targa input mode.
