Specifying meter in the header of the printed sheet

[Jan Kohnert]

Hello all,

I must be blind. I just cannot find how to specify the meter in the header 
correctly neither in the documentation nor in the web. :(

I know about the meter tag in the header section, but if I just type 
meter={138}, just the number is printed. But I want to have a quater note, 
folloed by '=' and then the number.

How can I get that output?
