Modules
module	metrics
	Module for reading in VMEC input and computing metric elements on the SIESTA (sqrt-flux) radial grid. Computes and stores the real-space metric elements, Jacobian based on square root of fluc splined vmec coordinate system.

subroutine	metrics::half_mesh_metrics (r1_i, ru_i, rv_i, z1_i, zu_i, zv_i)
	Compute the metric elements on the half mesh. More...
subroutine	metrics::full_mesh_metrics
	Gets the full grid metric elements. More...
subroutine	metrics::toupper (xsubsij, xsubuij, xsubvij,
	Converts to contravariant component full grid. More...
subroutine	metrics::tolowerh (xsupsij, xsupuij, xsupvij,
