reset - this is normal usage, clear database and reread everything from files - time-consuming
caves - read in the caves
logbooks - read in just the logbooks
people - read in the people from folk.csv
QMs - read in the QM csv files
reload_db - clear database (delete everything) and make empty tables
scans - NOT the scanned surveynotes ?!
survex - read in the survex files - all the survex blocks
surveys - read in the scanned surveynotes
tunnel - read in the Tunnel files - which scans the surveyscans too
survexpos - just the Pos out of the survex files (not part of reset)
resetend - (archaic?)
writecaves - *disabled* (archaic?)
autologbooks - read in autologbooks (what are these?)
dumplogbooks - write out autologbooks (not working?)
syncuser - needed after reloading database rom SQL backup
test - testing...
