/*! \file
* \brief addXMLinJP2 is a program to embed metadata into JP2 file
*
* \section impinst Implementing instructions
* This program takes two arguments. \n
* -# Input/output image file in JP2 format, this JP2 file is being modified
* -# Input XML file with metadata contents\n
* % ./addXMLinJP2 image.jp2 metadata.xml\n
*
* Currently, this program does not parse XML file, and the XML file contents is directly embedded as a XML Box.\n
* The following is an example of XML file contents specifying Region Of Interests with target names.\n
* <xmlbox>\n
* <roi name="island" x="1890" y="1950" w="770" h="310"/>\n
* <roi name="ship" x="750" y="330" w="100" h="60"/>\n
* <roi name="airport" x="650" y="1800" w="650" h="800"/>\n
* <roi name="harbor" x="4200" y="1650" w="130" h="130"/>\n
* </xmlbox>
