3# This is a utility that searches out "DECLARE_STACK_OF()"
4# declarations in .h and .c files, and updates/creates/replaces
5# the corresponding macro declarations in crypto/stack/safestack.h.
6# As it's not generally possible to have macros that generate macros,
7# we need to control this from the "outside", here in this script.
