Warning: This is an example potential. Please do NOT use it for any real simulations!
This is a Stillinger-Weber potential that can be used in potfit.

Please note that there is only a single stiweb_lambda potential which contains
all required lamdba parameters. The number of parameters for the stiweb_lambda potential
depends on the total number of atom types.
The example potential can be generated with the following makeapot command:
makeapot -n 2 -i stiweb
