dump3d - dump .3d file contents in textual format
dump3d [ --survey=SURVEY ] [ --rewind ] [ --show-dates ] PROCESSED_SURVEY_DATA_FILE
Dump out the entries in a processed survey data file - useful for debugging, and also provides a textual format which is fairly easy to parse if you want to write a simple script to pull out information from a file. Note that this tool can actually be used to dump any format the "img" library can read, not just Survex .3d files.
