Have a look at GCPrevue. It can read Gerber, Postscript, HPGL and can
convert between them.

GCPrevue used to be a DOS software with an awkward user interface.
Now it is a Win software with a slightly more intuitive user
interface.

But it is for free and it is made by real professionals.

It is also a great utility to visualize and verify your Gerber
output!
