+# Exim is built by default to support the SMTP STARTTLS command, which implements
+# Transport Layer Security using SSL (Secure Sockets Layer). This requires you
+# must install the OpenSSL library package or the GnuTLS library. Exim contains
+# no cryptographic code of its own.
+
+# If you are running Exim as a (TLS) server, just building it with TLS support
+# is all you need to do, as tls_advertise_hosts is set to '*' by
+# default. But you are advised to create a suiteable certificate, and tell
+# Exim about it by means of the tls_certificate and tls_privatekey run
+# time options, otherwise Exim will create a self signed certificate on
+# the fly. If you are running Exim only as a (TLS) client, building it with
+# TLS support is all you need to do.
+#
+# If you are using pkg-config then you should not need to worry where
+# the libraries and headers are installed, as the pkg-config .pc
+# specification should include all -L/-I information necessary.
+# Enabling the USE_*_PC options should be sufficient. If not using
+# pkg-config, then you have to specify the libraries, and you mmight
+# need to specify the locations too.
+
+# Uncomment the following lines if you want
+# to build Exim without any TLS support (either OpenSSL or GnuTLS):
+# DISABLE_TLS=yes
+# Unless you do this, you must define one of USE_OPENSSL or USE_GNUTLS
+# below.
+
+# If you are buliding with TLS, the library configuration must be done:
