A question out of ignorance on my side. Will/can the above directive be able to influence
/ somehow affect the ENGINE_ctrl_cmd_string() openssl call needed when using dynamic engines
in openssl (the "engine -pre" and "-post" options specifically)?

I've picked the pkcs11 support apart in openssl to discover that there are really two engines
at work, the "dynamic" engine capable of loading engines from dynamic libraries, and then
the "pkcs11" engine which is just an implementation that happens to be (if you use opensc
anyway) loadable as a dynamic library (this will be obvious to an openssl developer but wasn't
obvious to me from the documentation I've read to date, which doesn't make clear that two
engines are at work, or where the one engine begins and the other ends).

It would be nice to be able to kill-two-birds-with-one-directive if it makes sense to do so
(and entirely understand if it doesn't make sense).

Regards,
Graham
