=head1 DESCRIPTION
specifies the configuration file to use.
+=item B<-name section>
+
+specifies the configuration file section to use (overrides
+B<default_ca> in the B<ca> section).
+
=item B<-in filename>
an input filename containing a single certificate request to be
=item B<-spkac filename>
a file containing a single Netscape signed public key and challenge
-and additional field values to be signed by the CA. See the B<NOTES>
+and additional field values to be signed by the CA. See the B<SPKAC FORMAT>
section for information on the required format.
=item B<-infiles>
(using the default section unless the B<-extensions> option is also
used).
+=item B<-engine id>
+
+specifying an engine (by it's unique B<id> string) will cause B<req>
+to attempt to obtain a functional reference to the specified engine,
+thus initialising it if needed. The engine will then be set as the default
+for all available algorithms.

=head1 CRL OPTIONS
a filename containing a certificate to revoke.
+=item B<-crl_reason reason>
+
+revocation reason, where B<reason> is one of: B<unspecified>, B<keyCompromise>,
+B<CACompromise>, B<affiliationChanged>, B<superseded>, B<cessationOfOperation>,
+B<certificateHold> or B<removeFromCRL>. The matching of B<reason> is case
+insensitive. Setting any revocation reason will make the CRL v2.
+
+In practive B<removeFromCRL> is not particularly useful because it is only used
+in delta CRLs which are not currently implemented.
+
+=item B<-crl_hold instruction>
+
+This sets the CRL revocation reason code to B<certificateHold> and the hold
+instruction to B<instruction> which must be an OID. Although any OID can be
+used only B<holdInstructionNone> (the use of which is discouraged by RFC2459)
+B<holdInstructionCallIssuer> or B<holdInstructionReject> will normally be used.
+
+=item B<-crl_compromise time>
+
+This sets the revocation reason to B<keyCompromise> and the compromise time to
+B<time>. B<time> should be in GeneralizedTime format that is B<YYYYMMDDHHMMSSZ>.
+
+=item B<-crl_CA_compromise time>
+
+This is the same as B<crl_compromise> except the revocation reason is set to
+B<CACompromise>.
+
=item B<-subj arg>
-supersedes subject name given in the request
+supersedes subject name given in the request.
+The arg must be formatted as I</type0=value0/type1=value1/type2=...>,
+characters may be escaped by \ (backslash), no spaces are skipped.
=item B<-crlexts section>
=head1 CONFIGURATION FILE OPTIONS
-The options for B<ca> are contained in the B<ca> section of the
-configuration file. Many of these are identical to command line
+The section of the configuration file containing options for B<ca>
+is found as follows: If the B<-name> command line option is used,
+then it names the section to be used. Otherwise the section to
+be used must be named in the B<default_ca> option of the B<ca> section
+of the configuration file (or in the default section of the
+configuration file). Besides B<default_ca>, the following options are
+read directly from the B<ca> section:
+ RANDFILE
+ preserve
+ msie_hack
+With the exception of B<RANDFILE>, this is probably a bug and may
+change in future releases.
+
+Many of the configuration file options are identical to command line
options. Where the option is present in the configuration file
and the command line the command line value is used. Where an
option is described as mandatory then it must be present in
commonName = supplied
emailAddress = optional
-=head1 WARNINGS
-
-The B<ca> command is quirky and at times downright unfriendly.
-
-The B<ca> utility was originally meant as an example of how to do things
-in a CA. It was not supposed to be used as a full blown CA itself:
-nevertheless some people are using it for this purpose.
-
-The B<ca> command is effectively a single user command: no locking is
-done on the various files and attempts to run more than one B<ca> command
-on the same database can have unpredictable results.
-
=head1 FILES
Note: the location of all files can change either by compile time options,
to rebuild the index file from all the issued certificates and a current
CRL: however there is no option to do this.
-CRL entry extensions cannot currently be created: only CRL extensions
-can be added.
-
V2 CRL features like delta CRL support and CRL numbers are not currently
supported.

The B<copy_extensions> option should be used with caution. If care is
not taken then it can be a security risk. For example if a certificate
request contains a basicConstraints extension with CA:TRUE and the
