masque 1.5

Lithography mask library

Masque README

Masque is a Python module for designing lithography masks.

The general idea is to implement something resembling the GDSII file-format, but with some vectorized element types (eg. circles, not just polygons), better support for E-beam doses, and the ability to output to multiple formats.
