Importing cell library into Electric 7.00

Hi Steve,

I was trying to test the functionality of Electric 7.00 on another 
3-party cell library. The library comes with two LEF files, ie. a 
technology LEF and a cell library LEF. After a little bit testing and 
code viewing, I got to know 7.00's LEF import function does not read 
technology LEF.  I don't know whether there is any way you know of that 
we can import a technology LEF into Electric.   Another question is why 
layer names are constrained that they must be prefixed with "POLY", 
"METAL-", "VIA" and "CONT".

cheers,
