/**@file
 * \brief Code for ofxconnect utility.  C++ example code
 *
 * the purpose of the ofxconnect utility is to server as example code for
 * ALL functions of libOFX that have to do with creating OFX files.
 *
 * ofxconnect prints to stdout the created OFX file based on the options
 * you pass it
 *
 * currently it will only create the statement request file.  you can POST
 * this to an OFX server to request a statement from that financial
 * institution for that account.
 *
 * In the hopefully-not-to-distant future, ofxconnect will also make the
 * connection to the OFX server, post the data, and call ofxdump itself.
