garmin_save_runs retrieves track logs from a Garmin Forerunner device connected to an USB port, and saves the information into files. Files are saved with the extension ".gmn" and are named by the run start time (e.g. '20070121T151814.gmn'). The .gmn file format is a binary file format that can be unpacked with he garmin_dump or garmin_gmap utilities. It is substantially more efficient than the bloated XML format that Garmin uses.
The output of garmin_save_runs will tell you where on your filesystem the actual .gmn files were saved. The default is to save them in a directory tree (by year and month) under the current directory. You can override this by setting the environment variable GARMIN_SAVE_RUNS to whatever directory you like. Existing files are not overwritten.
