[NTG-context] Alignments side by side

[David Arnold]

All,

I am wondering how I can put two alignment environments side-by-side?

For test purposes, it's OK to use this twice.

\placeformula[-]
\startformula
\eqalign{
   f(x)&=x^2-2x-3\cr
   f(x)&=x^02x+1-1-3\cr
   f(x)&=(x-1)^2-4}
\stopformula

I'd like to get two of these side-by-side, or something that will  
typeset a similar result side-by-side.

Thanks.
