       exempi - command line tool to manipulate XMP metadata

       -h: show this help

       -R: don't reconcile

       -x: dump XML

       -p: wrap XML packet wrapper. Only for -x.

       -X: file(s) is XMP

       -w: write in place. Only for -s. Not compatible with -o.

       -o <file>: file to write the output to.

       -n <ns> <prefix>: set the prefix for a namespace.

       -g <prop_name>: retrieve the value with prop_name.

       -s <prop_name> -v <value>: retrieve or get the value.

       <files> the files to read from.

       The source code hasn't been audited for security. The command line  tool  doesn't  have  a  strong  input
       sanity checking easier.

       Be  careful  not  to  run  the  tool as super-user. Be careful if you decide to use it in an online (web)
       application.

       Patches and suggestions welcome.
