NAME
       g_sigeps - convert c6/12 or c6/cn combinations to and from sigma/epsilon

       VERSION 4.5.4-dev-20110404-bc5695c

DESCRIPTION
	g_sigeps is a simple utility that converts C6/C12 or C6/Cn combinations to sigma and epsilon, or vice versa. It can also plot  the  poten-
       tial in	file. In addition, it makes an approximation of a Buckingham potential to a Lennard-Jones potential.
