=head1 DESCRIPTION
SMIME_write_PKCS7() adds the appropriate MIME headers to a PKCS#7
structure to produce an S/MIME message.
-B<out> is the BIO to write the data to. B<p7> is the appropriate
-B<PKCS7> structure. If cleartext signing (B<multipart/signed>) is
-being used then the signed data must be supplied in the B<data>
-argument. B<flags> is an optional set of flags.
+B<out> is the BIO to write the data to. B<p7> is the appropriate B<PKCS7>
+structure. If streaming is enabled then the content must be supplied in the
+B<data> argument. B<flags> is an optional set of flags.

SMIME_write_PKCS7() always base64 encodes PKCS#7 structures, there
