You can simply do :   -format=md5_gen(1066)

The backward compatible way  -for=md5-gen -sub=md5_gen(1066) has been left, 
but the -sub= is not really needed any more.  The one thing I 'like' fom 
the -subformat is -sub=list   That command lists all the md5-gen format's 
installed on the machine.  That is the main reason (along with backward 
compatibility if people have scripts) that I kept the -subformat= command 
line switch at all.

the -subformat is not required (the format will deal with it), but the 
parens still 'are'.  I could change that to md5_gen_1066, but that is a 
'change'.  Would this be problems for not providing backward compatibility?
