error: bad option 'topdir' at rpmrc

[Francois Belliard ELIOS <francois belliard elios-informatique fr>]

Hello,

I am trying to build a package in an other directory than /usr/src/redhat.
In my ".rpmrc" file, there is a line (like in the max-rpm doc)
   topdir:  /...mypath.../mybuild

It does not seem to work . I get the following error when launching 
rpmbuild :
   "error: bad option 'topdir' at /users/fbelliard/.rpmrc:1"

I tried also with the parameters
   builddir
   specdir
   rpmdir
   sourcedir
and it's the same error.

Is it a known bug or have i done something wrong ?
