.... Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.
If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.
Avoid warning from groff about undefined register 'F'.

Title "SMIME_WRITE_PKCS7 3"
way too many mistakes in technical documents.
\fBout is the \s-1BIO\s0 to write the data to. p7 is the appropriate \s-1PKCS7\s0 structure. If streaming is enabled then the content must be supplied in the \fBdata argument. flags is an optional set of flags.
If \s-1PKCS7_DETACHED\s0 is set then cleartext signing will be used, this option only makes sense for signedData where \s-1PKCS7_DETACHED\s0 is also set when PKCS7_sign() is also called.
If the \s-1PKCS7_TEXT\s0 flag is set \s-1MIME\s0 headers for type text/plain are added to the content, this only makes sense if \s-1PKCS7_DETACHED\s0 is also set.
If the \s-1PKCS7_STREAM\s0 flag is set streaming is performed. This flag should only be set if \s-1PKCS7_STREAM\s0 was also set in the previous call to \fBPKCS7_sign() or PKCS7_encrypt().
If cleartext signing is being used and \s-1PKCS7_STREAM\s0 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.
If streaming is performed the content is output in \s-1BER\s0 format using indefinite length constructed encoding except in the case of signed data with detached content where the content is absent and \s-1DER\s0 format is used.
