7# Purpose
8#
9# To test the code dependencies on individual curves in each test suite. This
10# is a verification step to ensure we don't ship test suites that do not work
11# for some build options.
12#
13# The process is:
14#       for each possible curve
15#           build the library and test suites with the curve disabled
16#           execute the test suites
17#
18# And any test suite with the wrong dependencies will fail.
19#
20# Usage: curves.pl
21#
22# This script should be executed from the root of the project directory.
