.... 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 "X509_ALGOR_dup 3"
way too many mistakes in technical documents.

\fBX509_ALGOR_set0() sets the algorithm \s-1OID\s0 of alg to aobj and the associated parameter type to ptype with value pval. If ptype is \fBV_ASN1_UNDEF the parameter is omitted, otherwise ptype and pval have the same meaning as the type and value parameters to ASN1_TYPE_set(). All the supplied parameters are used internally so must \s-1NOT\s0 be freed after this call.
\fBX509_ALGOR_get0() is the inverse of X509_ALGOR_set0(): it returns the algorithm \s-1OID\s0 in *paobj and the associated parameter in *pptype and *ppval from the AlgorithmIdentifier alg.
\fBX509_ALGOR_set_md() sets the AlgorithmIdentifier alg to appropriate values for the message digest md.
\fBX509_ALGOR_cmp() compares a and b and returns 0 if they have identical encodings and nonzero otherwise.
\fBX509_ALGOR_copy() copies the source values into the dest structs; making a duplicate of each (and free any thing pointed to from within *dest).
\fBX509_ALGOR_set0() and X509_ALGOR_copy() return 1 on success or 0 on error.
\fBX509_ALGOR_get0() and X509_ALGOR_set_md() return no values.
\fBX509_ALGOR_cmp() returns 0 if the two parameters have identical encodings and nonzero otherwise.
