gEDA-user: gerber to .dxf converter

[Dave N6NZ]

Is there any free (as in speech) software that will convert gerber to .dxf?

Reason: I have access to a laser cutter through the TechShop and am 
trying to work out a path to cut el-cheapo solder paste screens in 
acetate sheet or similar material.  I tried the path of creating a 
PostScript check plot and running the .ps through pstoedit, which looks 
promising, although I haven't tried to cut the resulting file yet. 
But... seems like a direct path from the gerber would be better instead 
of relying on the check plot and the inherent precision limitations of 
PostScript.  Or perhaps I underestimate the check plots?
