installing gnats

[S Ramesh]

i am installing gnats in my local machine. as per the
installation procedure in the


sitehttp://tux.anu.edu.au/Software/Gnats/texinfo-docs/gnats_4.html#SEC44

i just run the ./configure --with-full-gnats option. and i
runt he make all info. now i want to know what is this
GNATS_ROOT directory. where we have to create. as i
mentioned i run  the configure with the option as with full
gnats. so there is no need of intalling utilites and all
know. kinldy clarify my doubt.
