+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX

+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+

+#	Check for the existence of the -lsocket and -lnsl libraries.
+#	The order here is important, so that they end up in the right
+#	order in the command line generated by make.  Here are some
+#	special considerations:
+#	1. Use "connect" and "accept" to check for -lsocket, and
+#	   "gethostbyname" to check for -lnsl.
+#	2. Use each function name only once:  can't redo a check because
+#	   autoconf caches the results of the last check and won't redo it.
+#	3. Use -lnsl and -lsocket only if they supply procedures that
+#	   aren't already present in the normal libraries.  This is because
+#	   IRIX 5.2 has libraries, but they aren't needed and they're
+#	   bogus:  they goof up name resolution if used.
+#	4. On some SVR4 systems, can't use -lsocket without -lnsl too.
+#	   To get around this problem, check for both libraries together
+#	   if -lsocket doesn't work by itself.

+	    fields in certain cases. The emulator does not use the
+	    decoded size field, but <c>erl_interface</c> still does
+	    and is not helped by this workaround.</p>

+	    <p> By default <c>global</c> does <i>not</i> take any
+	    actions to restore a fully connected network when
+	    connections are lost due to network issues. This is
+	    problematic for all applications expecting a fully
+	    connected network to be provided, such as for example
+	    <c>mnesia</c>, but also for <c>global</c> itself. A
+	    network of overlapping partitions might cause the
+	    internal state of <c>global</c> to become inconsistent.
+	    Such an inconsistency can remain even after such
+	    partitions have been brought together to form a fully
+	    connected network again. The effect on other applications
+	    that expects that a fully connected network is maintained
+	    may vary, but they might misbehave in very subtle hard to
+	    detect ways during such a partitioning. </p> <p> In order
+	    to prevent such issues, we have introduced a <i>prevent
+	    overlapping partitions</i> fix which can be enabled using
+	    the <seeapp
+	    marker="kernel:kernel_app#prevent_overlapping_partitions"><c>prevent_overlapping_partitions</c></seeapp>
+	    <c>kernel(6)</c> parameter. When this fix has been
+	    enabled, <c>global</c> will actively disconnect from
+	    nodes that reports that they have lost connections to
+	    other nodes. This will cause fully connected partitions
+	    to form instead of leaving the network in a state with
+	    overlapping partitions. Note that this fix <i>has</i> to
+	    be enabled on <i>all</i> nodes in the network in order to
+	    work properly. Since this quite substantially changes the
+	    behavior, this fix is currently disabled by default.
+	    Since you might get hard to detect issues without this
+	    fix you are, however, <i>strongly</i> advised to enable
+	    this fix in order to avoid issues such as the ones
+	    described above. As of OTP 25 this fix will become
+	    enabled by default. </p>

+	    Responsiveness of processes executing on <c>normal</c> or
+	    <c>low</c> priority could suffer due to code purging or
+	    literal area removal on systems with a huge amount of
+	    processes. This since during these operations all
+	    processes on the system were scheduled for execution at
+	    once.</p>
+          <p>
+	    This problem has been fixed by introducing a limit on
+	    outstanding purge and copy literal requests in the
+	    system. By default this limit is set to twice the amount
+	    of schedulers on the system. This will ensure that
+	    schedulers will have enough work scheduled to perform
+	    these operations as quickly as possible at the same time
+	    as other work will be interleaved to a much higher
+	    degree. Performance of these operations will however be
+	    somewhat degraded due to the overhead of enforcing this
+	    limit compared to when using a very large limit.</p>
+          <p>
+	    This limit can be set by passing the <c>+zosrl</c>
+	    command line argument to <c>erl</c>, or by calling
+	    <c>erlang:system_flag(outstanding_system_requests_limit,
+	    NewLimit)</c>.</p>

+	    Dirty execution of a process in combination with an
+	    unlink signal from a port to the process could cause the
+	    signal queue of the process to enter into an inconsistent
+	    state. The result of the inconsistency typically caused a
+	    crash of the runtime system. This bug was introduced in
+	    OTP 23.3 (ERTS version 11.2).</p>

+ * passed as third argument to point to it.
+ *
+ * If this function returns a reference, 'func' will
+ * be called in the context of the receiver. However,
+ * note that this might happen when the receiver is in
+ * an exiting state. The caller of this function
+ * *unconditionally* has to enter a receive that match
+ * on the returned reference in all clauses as next
+ * receive; otherwise, bad things will happen!

+     *
+     * Analysis: The longest fixed codes are a length code of 8 bits plus 5
+     * extra bits, for lengths 131 to 257. The longest fixed distance codes are
+     * 5 bits plus 13 extra bits, for distances 16385 to 32768. The longest

+     *
+     * sym_buf starts one-fourth of the way into pending_buf. So there are
+     * three bytes in sym_buf for every four bytes in pending_buf. Each symbol
+     * in sym_buf is three bytes -- two for the distance and one for the
+     * literal/length. As each symbol is consumed, the pointer to the next
+     * sym_buf value to read moves forward three bytes. From that symbol, up to
+     * 31 bits are written to pending_buf. The closest the written pending_buf
+     * bits gets to the next sym_buf symbol to read is just before the last
+     * code is written. At that time, 31*(n-2) bits have been written, just
+     * after 24*(n-2) bits have been consumed from sym_buf. sym_buf starts at
+     * 8*n bits into pending_buf. (Note that the symbol buffer fills when n-1
+     * symbols are written.) The closest the writing gets to what is unread is
+     * then n+14 bits. Here n is lit_bufsize, which is 16384 by default, and
+     * can range from 128 to 32768.
+     *
+     * Therefore, at a minimum, there are 142 bits of space between what is
+     * written and what is read in the overlain buffers, so the symbols cannot
+     * be overwritten by the compressed data. That space is actually 139 bits,
+     * due to the three-bit fixed-code block header.
+     *
+     * That covers the case where either Z_FIXED is specified, forcing fixed
+     * codes, or when the use of fixed codes is chosen, because that choice
+     * results in a smaller compressed block than dynamic codes. That latter
+     * condition then assures that the above analysis also covers all dynamic

+# Configuration subroutine to validate and canonicalize a configuration type.
+# Supply the specified configuration type as an argument.
+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.

+# This file is supposed to be the same for all GNU packages
+# and recognize all the CPU types, system types and aliases
+# that are meaningful with *any* GNU software.
+# Each package is responsible for reporting which valid configurations
+# it does not support.  The user should be able to distinguish
+# a failure to support a valid configuration from a meaningless
+# configuration.
+
+# The goal of this file is to map all the various variations of a given
+# machine specification into a single specification in the form:
+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
+# It is wrong to echo any other type of specification.

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+  --enable-shlib-thread-safety  enable thread safety for build shared libraries
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a

+  LIBS        libraries to pass to the linker, e.g. -l<library>

+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+#	Check for the existence of the -lsocket and -lnsl libraries.
+#	The order here is important, so that they end up in the right
+#	order in the command line generated by make.  Here are some
+#	special considerations:
+#	1. Use "connect" and "accept" to check for -lsocket, and
+#	   "gethostbyname" to check for -lnsl.
+#	2. Use each function name only once:  can't redo a check because
+#	   autoconf caches the results of the last check and won't redo it.
+#	3. Use -lnsl and -lsocket only if they supply procedures that
+#	   aren't already present in the normal libraries.  This is because
+#	   IRIX 5.2 has libraries, but they aren't needed and they're
+#	   bogus:  they goof up name resolution if used.
+#	4. On some SVR4 systems, can't use -lsocket without -lnsl too.
+#	   To get around this problem, check for both libraries together
+#	   if -lsocket doesn't work by itself.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]
+  --libexecdir=DIR        program executables [EPREFIX/libexec]

+  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]

+  --with-gmp              use GNU MP (will search for it)
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

+      <p>
+        By default <c>global</c> does <i>not</i> take any actions to restore
+        a fully connected network when connections are lost due to network
+        issues. This is problematic for all applications expecting a fully
+        connected network to be provided, such as for example <c>mnesia</c>,
+        but also for <c>global</c> itself. A network of overlapping partitions
+        might cause the internal state of <c>global</c> to become inconsistent.
+        Such an inconsistency can remain even after such partitions have been
+        brought together to form a fully connected network again. The effect
+        on other applications that expects that a fully connected network is
+        maintained may vary, but they might misbehave in very subtle hard to
+        detect ways during such a partitioning.
+      </p>
+      <p>
+        In order to prevent such issues, we have introduced a <i>prevent
+        overlapping partitions</i> fix which can be enabled using the
+        <seeapp marker="kernel_app#prevent_overlapping_partitions">
+          <c>prevent_overlapping_partitions</c></seeapp> <c>kernel(6)</c>
+        parameter. When this fix has been enabled, <c>global</c> will actively
+        disconnect from nodes that reports that they have lost connections to
+        other nodes. This will cause fully connected partitions to form
+        instead of leaving the network in a state with overlapping partitions.
+        Note that this fix <i>has</i> to be enabled on <i>all</i> nodes in the
+        network in order to work properly. Since this quite substantially
+        changes the behavior, this fix is currently disabled by default. Since
+        you might get hard to detect issues without this fix you are, however,
+        <i>strongly</i> advised to enable this fix in order to avoid issues
+        such as the ones described above. As of OTP 25 this fix  will become
+        enabled by default.
+      </p>
+    </warning>
     <p>These services are controlled through the process
       <c>global_name_server</c> that exists on every node. The global
       name server starts automatically when a node is started.

+	    <p> By default <c>global</c> does <i>not</i> take any
+	    actions to restore a fully connected network when
+	    connections are lost due to network issues. This is
+	    problematic for all applications expecting a fully
+	    connected network to be provided, such as for example
+	    <c>mnesia</c>, but also for <c>global</c> itself. A
+	    network of overlapping partitions might cause the
+	    internal state of <c>global</c> to become inconsistent.
+	    Such an inconsistency can remain even after such
+	    partitions have been brought together to form a fully
+	    connected network again. The effect on other applications
+	    that expects that a fully connected network is maintained
+	    may vary, but they might misbehave in very subtle hard to
+	    detect ways during such a partitioning. </p> <p> In order
+	    to prevent such issues, we have introduced a <i>prevent
+	    overlapping partitions</i> fix which can be enabled using
+	    the <seeapp
+	    marker="kernel:kernel_app#prevent_overlapping_partitions"><c>prevent_overlapping_partitions</c></seeapp>
+	    <c>kernel(6)</c> parameter. When this fix has been
+	    enabled, <c>global</c> will actively disconnect from
+	    nodes that reports that they have lost connections to
+	    other nodes. This will cause fully connected partitions
+	    to form instead of leaving the network in a state with
+	    overlapping partitions. Note that this fix <i>has</i> to
+	    be enabled on <i>all</i> nodes in the network in order to
+	    work properly. Since this quite substantially changes the
+	    behavior, this fix is currently disabled by default.
+	    Since you might get hard to detect issues without this
+	    fix you are, however, <i>strongly</i> advised to enable
+	    this fix in order to avoid issues such as the ones
+	    described above. As of OTP 25 this fix will become
+	    enabled by default. </p>

+%% 1. When a node lose connection to another node it sends a
+%%    {lost_connection, LostConnNode, OtherNode} message to all
+%%    other nodes that it knows of.
+%% 2. When a lost_connection message is received the receiver
+%%    first checks if it has seen this message before. If so, it
+%%    just ignores it. If it has not seen it before, it sends the
+%%    message to all nodes it knows of. This in order to ensure
+%%    that all connected nodes will receive this message. It then
+%%    sends a {remove_connection, LostConnRecvNode} message (where
+%%    LostConnRecvNode is its own node name) to OtherNode and
+%%    clear all information about OtherNode so OtherNode wont be
+%%    part of ReceiverNode's cluster anymore. When this information
+%%    has been cleared, no lost_connection will be triggered when
+%%    a nodedown message for the connection to OtherNode is
+%%    received.
+%% 3. When a {remove_connection, LostConnRecvNode} message is
+%%    received, the receiver node takes down the connection to
+%%    LostConnRecvNode and clears its information about
+%%    LostConnRecvNode so it is not part of its cluster anymore.
+%%    Both nodes will receive a nodedown message due to the
+%%    connection being closed, but none of them will send
+%%    lost_connection messages since they have cleared information
+%%    about the other node.
+%%
+%% This will take down more connections than the minimum amount
+%% of connections to remove in order to form fully connected
+%% partitions. For example, if the user takes down a connection
+%% between two nodes, the rest of the nodes will disconnect from
+%% both of these nodes instead of just one. This is due to:
+%% * We do not want to partition a remaining network when a node
+%%   has halted. When you receive a nodedown and/or lost_connection
+%%   messages you don't know if the corresponding node has halted
+%%   or if there are network issues.
+%% * We need to decide which connection to take down as soon as
+%%   we receive a lost_connection message in order to prevent
+%%   inconsistencies entering global's state.
+%% * All nodes need to make the same choices independent of
+%%   each other.

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]

+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

 %% Purpose: Help funtions for handling certificat verification.
 %% The path validation defined in ssl_handshake.erl that mainly
 %% calls functions in this module is described in RFC 3280. 
-%%----------------------------------------------------------------------
+%% The basic verification checks are done by
+%% public_key:pkix_path_validation/3
+%%
+%% TLS code handles construction of alternative certificate paths
+%% that can be used as input to public_key:pkix_path_validation/3
+%% to try and find one path that is considerd valid.
+%%
+%% The TLS protocol will send certificate chains that should consist
+%% of [PeerCert, CA0 ... CAN, ROOTCert]. The path will be the reverse of the
+%% chain and ROOTCert is the trusted anchor in the path validation.
+%% Also to complicate matters ROOTCerts can be left out of the sent chain.
+%% However due to configuration error and workarounds for certificate
+%% renewal purposes we have to handle chains that may be:
+%%
+%% * Unordered - PeerCert will still be first but the other certs
+%% may be arbitrarily order. Ex: [PeerCert, CAN ...  ROOTCert, CA0]
+%%
+%% * Partial - User decides to put the trust in an intermediate CA
+%% that is this intermediate CA must be part of the original chain
+%% and is used as the trusted anchor cert instead of the ROOT certificate.
+%% Ex: [PeerCert, CA0 ...CAN-1] instead of  [PeerCert, CA0 ...CAN, ROOTCert]
+%%
+%% * Incomplete - The chain sent is missing one or more certificates
+%% but if we have the missing certificates in our trust store we can recreate
+%% the chain. Ex:  [PeerCert, CA0 ...CAN-1] and CN and ROOTCert is in our
+%% trust store.
+%%
+%% * Extraneous - Contain extra certificates that are so called cross signed
+%% to enable construction of different cert chains depending on what is in the
+%% trust store. Used to phase out certificates that are expiring. So that
+%% a window can be created when there is an old about to expire cert and
+%% a new replacing cert that can coexist.
+%% Ex:  [PeerCert, CA0 ...CAN, CAN', ROOTCert]
+%%
+%% * Cross signed ROOT - Means looking for alternative paths using possible
+%% alternative ROOT certs if the original ROOT cert has expired or is unknown.

+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]
+  --libexecdir=DIR        program executables [EPREFIX/libexec]
+  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
+  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
+  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
+  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
+  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
+  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
+  --infodir=DIR           info documentation [DATAROOTDIR/info]
+  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
+  --mandir=DIR            man documentation [DATAROOTDIR/man]
+  --docdir=DIR            documentation root [DATAROOTDIR/doc/PACKAGE]

+  --with-wx-exec-prefix=PREFIX
+                          Exec prefix where wxWidgets is installed (optional)
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
+
+Report bugs to the package provider.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
