30  * Administration for metaslot
31  *
32  * All the "list" operations will call functions in libpkcs11.so
33  * Normally, it doesn't make sense to call functions in libpkcs11.so directly
34  * because libpkcs11.so depends on the configuration file (pkcs11.conf) the
35  * cryptoadm command is trying to administer.  However, since metaslot
36  * is part of the framework, it is not possible to get information about
37  * it without actually calling functions in libpkcs11.so.
38  *
39  * So, for the listing operation, which won't modify the value of pkcs11.conf
40  * it is safe to call libpkcs11.so.
41  *
42  * For other operations that modifies the pkcs11.conf file, libpkcs11.so
43  * will not be called.
