Convert.exe is a utility that converts .dfm files to .txt 
files and vice versa. Usage is simple:

	to convert from dfm to txt: convert unit.dfm
	to convert from txt to dfm: convert unit.txt

you can also specify multiple files:

	convert unit.txt unit2.txt unit3.txt

	convert unit.txt unit2.dfm unit3.dfm unit4.txt

and it will do the conversions automatically to the opposite
format.
