Side By Side Graphics But One Caption

[Bruce Pourciau]

How can I insert two figures (graphics) side by side, but with just  
one caption and figure number? I know from the Wiki how to have side  
by side figures with two separate captions, either Figure 1 and 2 or  
Figures 1a and 1b, but I'd prefer a single caption and figure number  
underneath the two figures.

Thanks,
Bruce
