# Makefile for freesurface continuator project
#
# Builds the lua libraries required for free surface continuation
# with integral methods based on GSL special functions
#
# Revision notes:
#
# 1/3/2013  Phased out wnl and wnl_global, phasing out integrals_hfall, and
#     integrals_triangle.
# 1/4/2017  Phased out integrals_hfall, integrals_box and integrals_triangle
# 12/4/2017 Updated clean procedure
