+# Library to extract EXIF information from digital camera image files
+# http://sourceforge.net/projects/exif-py/
+#
+# VERSION 1.1.0
+#
+# To use this library call with:
+#    f = open(path_name, 'rb')
+#    tags = EXIF.process_file(f)
+#
+# To ignore MakerNote tags, pass the -q or --quick
+# command line arguments, or as
+#    tags = EXIF.process_file(f, details=False)
+#
+# To stop processing after a certain tag is retrieved,
+# pass the -t TAG or --stop-tag TAG argument, or as
+#    tags = EXIF.process_file(f, stop_tag='TAG')
+#
+# where TAG is a valid tag name, ex 'DateTimeOriginal'
+#
+# These 2 are useful when you are retrieving a large list of images
+#
+#
+# To return an error on invalid tags,
+# pass the -s or --strict argument, or as
+#    tags = EXIF.process_file(f, strict=True)
+#
+# Otherwise these tags will be ignored
+#
+# Returned tags will be a dictionary mapping names of EXIF tags to their
+# values in the file named by path_name.  You can process the tags
+# as you wish.  In particular, you can iterate through all the tags with:
+#     for tag in tags.keys():
+#         if tag not in ('JPEGThumbnail', 'TIFFThumbnail', 'Filename',
+#                        'EXIF MakerNote'):
+#             print "Key: %s, value %s" % (tag, tags[tag])
+# (This code uses the if statement to avoid printing out a few of the
+# tags that tend to be long or boring.)
+#
+# The tags dictionary will include keys for all of the usual EXIF
+# tags, and will also include keys for Makernotes used by some
+# cameras, for which we have a good specification.
+#
+# Note that the dictionary keys are the IFD name followed by the
+# tag name. For example:
+# 'EXIF DateTimeOriginal', 'Image Orientation', 'MakerNote FocusMode'
