+The text printed is the same whether selected with the @code{help} option
+(@option{--help}) or the @code{more-help} option (@option{--more-help}).  @code{more-help} will print
+the usage text by passing it through a pager program.
+@code{more-help} is disabled on platforms without a working
+@code{fork(2)} function.  The @code{PAGER} environment variable is
+used to select the program, defaulting to @file{more}.  Both will exit

+@subsubheading local option.
+@anchor{danetool local}
+
+This is an alias for the @code{domain} option,
+@pxref{danetool domain, the domain option documentation}.
+
+@subsubheading domain option.
+@anchor{danetool domain}

+This is the ``the provided certificate or public key is issued by the local domain'' option.
+
+@noindent
+This option has some usage constraints.  It:
+@itemize @bullet
+@item
+can be disabled with --no-domain.
+@item
+It is enabled by default.
+@end itemize
+
+DANE distinguishes certificates and public keys offered via the DNSSEC to trusted and local entities. This flag indicates that this is a domain-issued certificate, meaning that there could be no CA involved.
+@subsubheading local-dns option.
+@anchor{danetool local-dns}
+
+This is the ``use the local dns server for dnssec resolving'' option.

+
+This is the ``do not verify any dnssec signature'' option.
+Ignores any DNSSEC signature verification results.
+@subsubheading inder option.
+@anchor{danetool inder}
+
+This is the ``use der format for input certificates and private keys'' option.

+@subsubheading DANE TLSA RR generation
+
+To create a DANE TLSA resource record for a certificate (or public key) 
+that was issued localy and may or may not be signed by a CA use the following command.
+@example
+$ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem
+@end example
+
+To create a DANE TLSA resource record for a CA signed certificate, which will
+be marked as such use the following command.
+@example
+$ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem \
+  --no-domain
+@end example
+
+The former is useful to add in your DNS entry even if your certificate is signed 
+by a CA. That way even users who do not trust your CA will be able to verify your
+certificate using DANE.
+
+In order to create a record for the CA signer of your certificate use the following.
+@example
+$ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem \
+  --ca --no-domain
+@end example
+
+To read a server's DANE TLSA entry, use:
+@example
+$ danetool --check www.example.com --proto tcp --port 443
+@end example
+
+To verify an HTTPS server's DANE TLSA entry, use:
+@example
+$ danetool --check www.example.com --proto tcp --port 443 --load-certificate chain.pem
+@end example
+
+To verify an SMTP server's DANE TLSA entry, use:
+@example
+$ danetool --check www.example.com --proto tcp --starttls-proto=smtp --load-certificate chain.pem
+@end example
