This directory contains all the code for this thorn which "knows" about
general relativity.

The main source files in this directory are as follows:

driver.cc
	Top-level driver for the whole thorn.

horizon_function.cc
	Computes the LHS of the AH equation, $H = H(h)$.

horizon_Jacobian.cc
	Computes the Jacobian of the $H(h)$ function, $J[H(h)]$.

AHFinderDirect.hh
	Overall header file for all the external routines in this directory.

gfns.hh
	Defines the gfns of all the gridfns as enums in namespace gfns::.

cg.hh
	This is a "dangerous" header file which defines the "virtual machine"
	used by the machine-generated code in ../gr.cg/.

doit.maple
	Top-level driver for all the Maple code.

setup_gr_gfas.maple
gr_gfas.minc
	These files define the relativity gridfns for the Maple code,
	eg the 3-metric, 3-extrinsic curvature, etc.

auxiliary.maple
curvature.maple
horizon.maple
	These files compute the $H(h)$ function and the $J[H(h)]$
	coefficients in Maple.

maple.log
	This is a log file (transcript) of the Maple computation.
