Only place where I found eps2 is <file:///usr/local/share/doc/ 
ImageMagick-6.2.6/www/formats.html>, but it doesn't say much more as  
telling that's PostScript Level 2.

As to the syntax eps2:filename.eps to specify the output file  
filename.eps must be in eps2 format whatever the extension, I  
couldn't find any clear explanation of it. The closer to an  
explanation is, in <file:///usr/local/share/doc/ImageMagick-6.2.6/www/ 
command-line-processing.html>

and in <file:///usr/local/share/doc/ImageMagick-6.2.6/www/command- 
line-options.html#format>

but I wouldn't call that explicit.
