Tim,

I tried what you suggested, but I get an error when my
tech file is read into magic.  My cifinput looks like
this:

style default
	scalefactor 1 calmaonly nanometers
	layer ndiff CDF
	layer poly PLY
	calma CDF 6 30
	calma PLY 17 30


And I get this message:
/space/CAD/lib/magic/sys/mytech.tech27: line 1595:
section cifinput:
        Wrong number of arguments in scalefactor
statement.
/space/CAD/lib/magic/sys/mytech.tech27: line 2464:
section cifinput:
        CIF input style "default" bad scalefactor;
using 1.
/space/CAD/lib/magic/sys/mytech.tech27: line 2464:
section cifinput:

Also, if I do a grep for "nanometers" in the source
code tree, it comes up empty.  The 7.1 distribution I
got was from the vlsi.cornell.edu page and named
"magic-latest."  Is the source on your site newer? 
How can I tell?  I can't find any versioning beyond
7.1 attached to my distribution.

Thanks,

Brad
