problem after cvsimport

I am new to git, so probably doing something wrong.
Hope somebody can enlighten me.
Here is what happened so far.

Followed instructions here:
http://www.kernel.org/pub/software/scm/git/docs/cvs-migration.html

Did command like this:

$ git cvsimport -C <destination> <module>

This was done from top level of existing cvs working directory.
Destination was new empty directory, outside the cvs tree.

It worked for several hours and seemed to complete ok.
I can look at history in destination git directory with gitk and git log.
All the stuff in ".git" looks normal, as far as I can tell.

But I have no files in the working directory.
When I do command:
$git checkout master

I get a bunch of lines to console with "D" in front.
Btw, what does that mean?  Nothing about it in "man git-checkout" or elsewhere that I can find.
Then it says -- Already on branch "master"

But working directory is still empty.


Thanks much,
Bert Douglas
