-CTLOG_new() returns a new CTLOG that represents the Certificate Transparency
-(CT) log with the given public key. A name must also be provided that can be
-used to help users identify this log. Ownership of the public key is
-transferred.
+CTLOG_new_with_libctx() returns a new CTLOG that represents the Certificate
+Transparency (CT) log with the given public key and associates it with the
+library context I<libctx> and property query string I<propq>. A name must also
+be provided that can be used to help users identify this log. Ownership of the
+public key is transferred.
+
+CTLOG_new() does the same thing as CTLOG_new_with_libctx() but with the default
+library context and the default property query string.
+
+CTLOG_new_from_base64_with_libctx() also creates a new CTLOG, but takes the
+public key in base64-encoded DER form and sets the ct_log pointer to point to
+the new CTLOG. The base64 will be decoded and the public key parsed. The CTLOG
+will be associated with the given library context I<libctx> and property query
+string I<propq>.

+CTLOG_new_from_base64() does the same thing as
