Running the DRC script:

1. To use the DRC script, source sourceme
2. Then, the "run_calibreDRC" script can either be executed on one gds layout file or the entire gds catalog found in "../lib/gds" directory.

Example, to run DRC on all gds files use this nomenclature for the command "./run_calibreDRC". 
Example 2, If a specific cell is desired, run the following nomenclature "./run_calibreDRC cell_name.gds"
*Note: The gds layout file must be in the "../lib/gds" script in order to work.*
