28    # no-shared will disable building shared libcrypto and libssl libraries.
29    # But the legacy provider would still be built as a shared module.
30    # So you would need the legacy shared module present on the installed
31    # system and the paths would have to be correct.
32    # You can use no-module to make the legacy provider built-in.
