Build Git with Visual Studio 2008

I successfully build git with visual studio 2008.

I just simple test git-log is work right.
I want to submit my work to mail list.

But I have some questions.

I create directory "vcbuild" under root/git.
vcbuild include VS project file and some dumy head files and binary libzip.

But I found a contrib directory, does I should put "vcbuild" to
contrib directory.
