# The libsodium test suite is designed to be run each test case as an executable on a desktop computer and uses
# filesytem to write & then compare contents of each file.
#
# For now, use their "BROWSER_TEST" mode with these hacks so that
# multiple test cases can be combined into one ELF file.
#
# Run each test case from test_sodium.c as CASENAME_xmain().
