5This package consists of three utilities for displaying and modifying
6Exif tags in digital camera JPEG files:
7
8    1.  exiftags: spits out Exif tags;
9    2.  exifcom: displays and writes the UserComment tag; and
10    3.  exiftime: displays, adjusts, and writes date/time tags or lists
11        files in date/time order.
12
13See the included man pages for usage and more information.  If you want
14to read the man pages before installing, just do:
15
16    nroff -man exiftags.1 | more
17    nroff -man exifcom.1 | more
18    nroff -man exiftime.1 | more
19
20To build the programs, type:
21
22    make
23
24To install them (defaults to a prefix of /usr/local):
25
26    make install
27
28Included are Visual Studio workspace and project files which should
29be sufficient for building under Windows.  To install, just copy
30exiftags.exe, exifcom.exe, and exiftime.exe to some directory in your
31path (c:\windows\system32 usually works).
32
33It should build fine on FreeBSD, Linux, Solaris and Mac OS X using gcc;
34on Windows using Visual C++ 6.0 (and probably others).  Portability
35patches are welcomed.  You might have problems with the use of
36u_int16_t and u_int32_t.  If so, see exif.h.
37
38Feel free to use the source within the confines of its BSD license.  Note
39that I do not wish it to be re-licensed under some other Open Source
40license (e.g., GPL).  I would be interested to know if you use parts of
41this program in your own and any thoughts you might have on its
42improvement.
43
44If you know how to decode unsupported maker note data or are able to
45procure definitive information from a manufacturer, I'd love to hear
46from you.

48Please report bugs, incompatibilities, successes, etc. to
49emj@postal.net.  The latest version of this software will be posted
