+Jhead is a command line program for manipulating the non-image
+parts of Exif JPEG files that most digital cameras produce.  
+
+By default, jhead displays the more useful camera settings from the
+file, but it can also be used to perform operations such as changing
+timestamps or removing a thumbnail.
+
+Though there are many programs out there now that can manipulate
+Exif headers today, for many tasks, jhead remains the simplest and
+most effective tool for the job, especially if used for automated
+or scripted tasks.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
