+# This parser parses the output from Phil Harvey's exiftool (version 9.02)
+# and convert it to xml format. It reads exiftool's output from stdin and
+# write the xml format to stdout.
+#
+# In order to get the raw infomation from exiftool, we need to enable the verbose
+# flag (-v2) of exiftool.
+#
+# Usage:
+#      exiftool -v2 img.jpg | ./parser.py >> output.xml
