This program edits GPX files of individual geocaches, downloaded from http://www.geocaching.com and marks them as "geocache found" id the GC code of the geocache is present in the My Finds Pocket Query file, also downloaded from geocaching.com.
I created this program because my Garmin Oregon 600 GPS receiver stopped marking geocaches as found. So instead of relying on the Oregon to keep track of found geocaches I run this program.
