-// A subgroup of the group of points on an elliptic curve.
-// Also used to represent quotient groups.
-//
-// We use the field_t structure even though E(K) is a group. Addition and
-// multiplication both refer to the group operation.
-
-// Requires:
-// * stdio.h
-// * gmp.h
-// * field.h
-#ifndef __PBC_CURVE_H__
-#define __PBC_CURVE_H__
-
-// Some initialization functions take an order parameter. This is meant to
-// be the order of the subgroup, but might actually be the order of the twist.
-// Certain routines initialize a curve, test a random point to see if it has
-// the correct order, and if not, immediately twist the curve so that it does.
-// TODO: Move such code into curve.c, so 'order' is always accurate.
-
-// If cofac != NULL, then the field_t represents the subgroup of
-// order = #E(K) / cofac.
-//
-// If not, and order = #E(K) then the field_t represents the entire E(K).
-//
-// Otherwise, if order is a factor of #E(K), then the field_t represents
-// the quotient group of that order, namely E(K)/(#E(K)/order). No attempt is
-// made to standardize the coset representative. This mode is useful for the
-// Tate pairing (see thesis), where any coset representative of G2 suffices
-// during the pairing computation.
