If you're just curious to access them for non-editing purposes, you can easily do that in game using these commands:
For vehicles (replace "M113" with whatever classname you want):
getText (configFile >> "CfgVehicles" >> "M113" >> "Library" >> "libTextDesc")
For weapons (replace "M16A4_ACG_GL" with whatever weapon classname you want):
getText (configFile >> "CfgWeapons" >> "M16A4_ACG_GL" >> "Library" >> "libTextDesc")
Have fun!
Wolfrug out.
