This is GDS2, a module for quickly creating programs to read, 
write, and manipulate GDS2 (GDSII) stream files.

use cpansign -v to check file integrity

GDS2 should be able to handle any size gdsii file but
I would consider it too slow for anything larger 
than a few megabytes in size. If your files are are
closer to the gigabyte range you should check out my 
gdt programs at:
http://sourceforge.net/projects/gds2/
which you can open and process as a pipe from Perl.
