Starting Gnome

[Halley Clark <halley_clark mac com>]

I am new to the X11 windowing system having all of my experience with 
command line interface AIX and Solaris systems. I have installed Gnome 
on my system, but i need to know how to start it.  There is no easy to 
figure out "startkde" type of comand in the bin directory where the 
rest of gnome is. What do I enter at the command line or into the 
.xinitrc file to start gnome?

Thanks,

Halley Clark
