function arguments as subscripts

Hello!

Mathematica lets me define functions that take their arguments as
subscripts. For example:

In[16]:=
   \!\(foo\_\(k_, l_\) = k l\)

In[17]:=
   \!\(foo\_\(3, 4\)\)

Out[17]=
   12

However, I can't seem to figure out how to define such a function in a
package. In particular, I am unable to define a ::usage for any function
taking an argument as a subscript.

Any suggestions on how to do this?

Thanks,

  Henrik Weimer
