* GSSAPI documentation
*
* This version will attempt to perform a GSSAPI handshake first; if this
* fails, then it will attempt standard POP authentication. Note that
* library conflicts may prevent the use of this with the Kerberos
* kpop hack.
*
* If you specify POP_NO_NOPROT and this library is unable to provide either
* integrity protection or encryption, pop_open() will fail. The pop_open()
* call will attempt the highest level protection available; i.e., if both
* server and client support encryption (and you do not provide the
* POP_NO_ENCRYPT flag), that will be used; if both server and client support
* integrity protection (and you do not provide the POP_NO_INTEG flag), that
* will be used. If neither of these are available, and you have not
* specified the POP_NO_NOPROT flag, then this will be a normal, unprotected
* connection.
