-# SYNOPSIS
-#
-#   ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
-#
-# DESCRIPTION
-#
-#   This macro figures out how to build C programs using POSIX threads.
-#   It sets the PTHREAD_LIBS output variable to the threads library and
-#   linker flags, and the PTHREAD_CFLAGS output variable to any special
-#   C compiler flags that are needed. (The user can also force certain
-#   compiler flags/libs to be tested by setting these environment
-#   variables.)
-#
-#   Also sets PTHREAD_CC to any special C compiler that is needed for
-#   multi-threaded programs (defaults to the value of CC otherwise).
-#   (This is necessary on AIX to use the special cc_r compiler alias.)
-#
-#   NOTE: You are assumed to not only compile your program with these
-#   flags, but also link it with them as well. e.g. you should link
-#   with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
-#   $LIBS
-#
-#   If you are only building threads programs, you may wish to use
-#   these variables in your default LIBS, CFLAGS, and CC:
-#
-#          LIBS="$PTHREAD_LIBS $LIBS"
-#          CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
-#          CC="$PTHREAD_CC"
-#
-#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
-#   constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
-#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
-#
-#   ACTION-IF-FOUND is a list of shell commands to run if a threads
-#   library is found, and ACTION-IF-NOT-FOUND is a list of commands to
-#   run it if it is not found. If ACTION-IF-FOUND is not specified, the
-#   default action will define HAVE_PTHREAD.
-#
-#   Please let the authors know if this macro fails on any platform, or
-#   if you have any other suggestions or comments. This macro was based
-#   on work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/)
-#   (with help from M. Frigo), as well as ac_pthread and hb_pthread
-#   macros posted by Alejandro Forero Cuervo to the autoconf macro
-#   repository. We are also grateful for the helpful feedback of
-#   numerous users.

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also link it with them as well. e.g. you should link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threads programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+of the Ecdysis project.  The code is copyright by them, and has the BSD
+license (see the dns64/dns64.c file).
+
+To enable DNS64 functionality in Unbound, two directives in unbound.conf must
+be edited:
+
+1. The "module-config" directive must start with "dns64". For example:
+
+    module-config: "dns64 validator iterator"
+
+If you're not using DNSSEC then you may remove "validator".
+
+2. The "dns64-prefix" directive indicates your DNS64 prefix. For example:
+
+    dns64-prefix: 64:FF9B::/96
+
+The prefix must be a /96 or shorter.
+
+To test that things are working right, perform a query against Unbound for a
+domain name for which no AAAA record exists. You should see a AAAA record in
+the answer section. The corresponding IPv6 address will be inside the DNS64

+.P
+This tool provides builtin default contents for the root anchor and root
+update certificate files.
+.P
+It tests if the root anchor file works, and if not, and an update is possible,
+attempts to update the root anchor using the root update certificate.
+It performs a https fetch of root-anchors.xml and checks the results, if
+all checks are successful, it updates the root anchor file.  Otherwise
+the root anchor file is unchanged.  It performs RFC5011 tracking if the
+DNSSEC information available via the DNS makes that possible.
+.P
+It does not perform an update if the certificate is expired, if the network
+is down or other errors occur.
+.P
+The available options are:
+.TP
+.B \-a \fIfile
+The root anchor key file, that is read in and written out.
+Default is @UNBOUND_ROOTKEY_FILE@.
+If the file does not exist, or is empty, a builtin root key is written to it.
+.TP
+.B \-c \fIfile
+The root update certificate file, that is read in.
+Default is @UNBOUND_ROOTCERT_FILE@.
+If the file does not exist, or is empty, a builtin certificate is used.
+.TP
+.B \-l
+List the builtin root key and builtin root update certificate on stdout.
+.TP
+.B \-u \fIname
+The server name, it connects to https://name.  Specify without https:// prefix.
+The default is "data.iana.org".  It connects to the port specified with \-P.
+You can pass an IPv4 addres or IPv6 address (no brackets) if you want.
+.TP
+.B \-x \fIpath
+The pathname to the root\-anchors.xml file on the server. (forms URL with \-u).
+The default is /root\-anchors/root\-anchors.xml.
+.TP
+.B \-s \fIpath
+The pathname to the root\-anchors.p7s file on the server. (forms URL with \-u).
+The default is /root\-anchors/root\-anchors.p7s.  This file has to be a PKCS7
+signature over the xml file, using the pem file (\-c) as trust anchor.
+.TP
+.B \-n \fIname
+The emailAddress for the Subject of the signer's certificate from the p7s
+signature file.  Only signatures from this name are allowed.  default is
+dnssec@iana.org.  If you pass "" then the emailAddress is not checked.
+.TP
+.B \-4
+Use IPv4 for domain resolution and contacting the server on https.  Default is
+to use IPv4 and IPv6 where appropriate.
+.TP
+.B \-6
+Use IPv6 for domain resolution and contacting the server on https.  Default is
+to use IPv4 and IPv6 where appropriate.
+.TP
+.B \-f \fIresolv.conf
+Use the given resolv.conf file.  Not enabled by default, but you could try to
+pass /etc/resolv.conf on some systems.  It contains the IP addresses of the
+recursive nameservers to use.  However, since this tool could be used to
+bootstrap that very recursive nameserver, it would not be useful (since
+that server is not up yet, since we are bootstrapping it).  It could be
+useful in a situation where you know an upstream cache is deployed (and
+running) and in captive portal situations.
+.TP
+.B \-r \fIroot.hints
+Use the given root.hints file (same syntax as the BIND and Unbound root hints
+file) to bootstrap domain resolution.  By default a list of builtin root
+hints is used.  Unbound\-anchor goes to the network itself for these roots,
+to resolve the server (\-u option) and to check the root DNSKEY records.
+It does so, because the tool when used for bootstrapping the recursive
+resolver, cannot use that recursive resolver itself because it is bootstrapping
+that server.
+.TP
+.B \-v
+More verbose. Once prints informational messages, multiple times may enable
+large debug amounts (such as full certificates or byte\-dumps of downloaded
+files).  By default it prints almost nothing.  It also prints nothing on
+errors by default; in that case the original root anchor file is simply
+left undisturbed, so that a recursive server can start right after it.
+.TP
+.B \-C \fIunbound.conf
+Debug option to read unbound.conf into the resolver process used.
+.TP
+.B \-P \fIport
+Set the port number to use for the https connection.  The default is 443.
+.TP
+.B \-F
+Debug option to force update of the root anchor through downloading the xml
+file and verifying it with the certificate.  By default it first tries to
+update by contacting the DNS, which uses much less bandwidth, is much
+faster (200 msec not 2 sec), and is nicer to the deployed infrastructure.
+With this option, it still attempts to do so (and may verbosely tell you),
+but then ignores the result and goes on to use the xml fallback method.
+.TP
+.B \-h
+Show the version and commandline option help.
+.SH "EXIT CODE"
+This tool exits with value 1 if the root anchor was updated using the
+certificate or if the builtin root-anchor was used.  It exits with code
+0 if no update was necessary, if the update was possible with RFC5011
+tracking, or if an error occurred.
+.P
+You can check the exit value in this manner:
