a line under the header

[Helmut Schwertner <hschwert@gmx.de>]

Hello,

I would like to put a line (not [underbared]) under the header  and above
the footer. The line shouldn't be to thin (not so thin as \hairline) and it
would be nice, if I could have a coloured line (grey, red, whatever). A
small example, so something like this (best view with non proportional
font):


header					pagenumber
-------------------------------------------

text text text text text text text text
text   text text text text text text

text text  text text text text text



-----------------------------------------
footer					footer


Thanks for any help,

best wishes,

Helmut
