[texhax] Style location

[Konstantin Karapetyan]

Dear TeX users,

I have a sty file located in a directory above the project directory.
And I don't want to include it into the texmf tree. Therefore I call
the sty file with

\usepackage{../foo}.

Everything works fine but I get

LaTeX Warning: You have requested package `../foo',
               but the package provides `foo'.

In the foo.sty it is defined as

\ProvidesPackage{foo}[2005/05/20 v1.0b]

How do I get rid of this warning?

TIA!

Happy TeXing,
Konstantin.
