Footers with more than 1 line

[Pedro Martins]

If somebody could help me to solve this problem
I would be very appreciated:

I am getting very stressed with GROFF.
This time I am trying to print a page footer
that has more than 1 line.

I tried to to use .wh to call a macro with the
text I want to print.
The problem is, when I try to get this text to the
bottom of the page, GROFF puts it in the next page.

When I use .PF it works just fine, but I don't know
how to use it when I have more than 1line of text to print.

I am using the mm macro.

I apreciate your help.
