setuid question

[Johann Spies <jhspies@adept.co.za>]

Can somebody explain to me what setuid does?

I have installed Debian 2.2 and copied my old home(~) directory on to the
new installation.  The difference between the old home and the new one
is 

old: drwxr-xr-x
new: drwxr-sr-x

Now I can not as user run binaries situated in my own bin directory.

I thought a setup like that would allow only me or users of my group
to run binaries in my home directory.
