A code snippet follows from one of my DM files for my space game.
J_Unit
desc = "J-Units are standard spare parts. They yield a specific amount \
of resistance to a power connection system."
K_Unit
desc = "K-Units are standard spare parts. They operate as non-conductive \
cantilevers to support \"hot\" electrical systems."
L_Unit
desc = "L-Units are standard spare parts. They're very important units. \
Without them, space travel is but the fevered dream of a madman."
