1 | /* A little hacked up program that makes a TCP/IP call and reads a script to |
2 | drive it, for testing Exim server code running as a daemon. It's got a bit | |
3 | messy with the addition of support for either OpenSSL or GnuTLS. The code for | |
2b4a568d JH |
4 | those was hacked out of Exim itself, then code for OpenSSL OCSP stapling was |
5 | ripped from the openssl ocsp and s_client utilities. */ | |
