   2
   3 # 1.14.0 200501261830 - units can have different offsets, so we can convert ^C/^F
   4 # 1.13.1 200501071420 - added cd/dvd sizes to data storage
   5 # 1.13.0 200411042100 - changed calls addmenu() and redraw()
   6 # 1.11.0 200410291000 - use redraw()
   7 # 1.10.5 200410151900 - data storage units (8 total, including LOC)
   8 # 1.10.4 200410132300 - hp49 units for mass
   9 # 1.10.3 200410130000 - fix error when run without menu module
  10 # 1.10.2 200410122200 - adds submenus with all units
  11 # 1.10.1 200410122030 - hp49 units for area, volume, time, speed, force, energy, power
  12 # 1.09.2 200410112205 - all code moved here as well
  13 # 1.09.1 200410022305 - moved %unit specs from 1.9 main
