1 # unit convertor for DCT, by Shiar
3 # 1.09.1 200410022305 - moved %unit specs from 1.9 main
4 # 1.09.2 200410112205 - all code moved here as well
5 # 1.10.1 200410122030 - hp49 units for area, volume, time, speed, force, energy, power
6 # .2 2200 - adds submenus with all units
7 # .3 10130000 - fix error when run without menu module
8 # .4 10132300 - hp49 units for mass
