+=head1 NAME
+
+SMIME_write_PKCS7 - convert PKCS#7 structure to S/MIME format.
+
+=head1 SYNOPSIS
+
+int SMIME_write_PKCS7(BIO *out, PKCS7 *p7, BIO *data, int flags);
+
+=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.
+
+=head1 NOTES
+
+The following flags can be passed in the B<flags> parameter.
+
+If B<PKCS7_DETACHED> is set then cleartext signing will be used,
+this option only makes sense for signedData where B<PKCS7_DETACHED>
+is also set when PKCS7_sign() is also called.
+
+If the B<PKCS7_TEXT> flag is set MIME headers for type B<text/plain>
+are added to the content, this only makes sense if B<PKCS7_DETACHED>
+is also set.
+
+If the B<PKCS7_PARTSIGN> flag is set the signed data is finalized
+and output along with the content. This flag should only be set
+if B<PKCS7_DETACHED> is also set and the previous call to PKCS7_sign()
+also set these flags.
+
+If cleartext signing is being used and B<PKCS7_PARTSIGN> not set then
+the data must be read twice: once to compute the signature in PKCS7_sign()
+and once to output the S/MIME message.
+
+=head1 BUGS
+
+SMIME_write_PKCS7() always base64 encodes PKCS#7 structures, there
+should be an option to disable this.
+
+=head1 RETURN VALUES
+
+SMIME_write_PKCS7() returns 1 for success or 0 for failure.
