+ o added CURLINFO_OS_ERRNO
+ o added CURLOPT_FTPSSLAUTH to allow ftp connects to attempt "AUTH TLS" instead

-   showed a connect problem now fixed.
- o The generated ca-bundle.h file is now generated in the build dir, not the
-   source dir
- o The FTP-EPSV response parser for the 229 code was fixed
- o curl finds the user's home dir slightly different and hopefully better on
-   Windows
- o testcurl.sh can now be used to autotest daily tarballs
- o a couple of command line options now check that the underlying library
-   actually supports the features before trying to enable them
- o uninitialized variable fix

+ o CURLOPT_FTP_CREATE_MISSING_DIRS works for third party transfers
+ o memory leak for cookies received with max-age set
+ o potential memory leaks in the window name resolver
+ o URLs with ?-letters in the user name or password fields

-This package is built on ares 1.1.1 (written by Greg Hudson). I've decided to
-put together and release my own ares archives since the ares maintainer
-doesn't want these improvements.
+  Changelog for the c-ares project
 
-The package is called 'c-ares' for now since I (Daniel Stenberg) want this for
-use within the curl project (hence the letter C) and it makes a nice pun.
+* September 29
 
-* January 4, 2004:
+- Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital
+  when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for
+  other OSes. He made c-ares check for and understand it if present.
+
+- Now c-ares will use local host name lookup _before_ DNS resolving by default
+  if nothing else is told.
+
+* September 26
+
+- Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf
+  file to determine the sequence in which to search /etc/hosts and DNS.  So on
+  systems where this order is defined by /etc/host.conf instead of a "lookup"
+  entry in /etc/resolv.conf, c-ares will always default to looking in DNS
+  first, and /etc/hosts second.
+
+  c-ares now looks at
+
+  1) resolv.conf (for the "lookup" line);
+  2) nsswitch.fon (for the "hosts:" line);
+  3) host.conf (for the "order" line).
+
+  First match wins.
+
+- Dominick Meglio patched: C-ares on Windows assumed that the HOSTS file is
+  located in a static location. It assumed
+  C:\Windows\System32\Drivers\Etc. This is a poor assumption to make. In fact,
+  the location of the HOSTS file can be changed via a registry setting.
+
+  There is a key called DatabasePath which specifies the path to the HOSTS
+  file:
+  http://www.microsoft.com/technet/itsolutions/network/deploy/depovg/tcpip2k.mspx
+
+  The patch will make c-ares correctly consult the registry for the location
+  of this file.
+
+* August 29
+
+- Gisle Vanem fixed the MSVC build files.
+
+* August 20
+
+- Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack.
+
+* August 13
+
+- Harshal Pradhan made a minor syntax change in ares_init.c to make it build
+  fine with MSVC 7.1
+
+* July 24
+
+- Made the lib get built static only if --enable-debug is used.
+
+- Gisle Vanem fixed:
+
+  Basically in loops like handle_errors(), 'query->next' was assigned a local
+  variable and then query was referenced after the memory was freed by
+  next_server(). I've changed that so next_server() and end_query() returns
+  the next query. So callers should use this ret-value.
+
+  The next problem was that 'server->tcp_buffer_pos' had a random value at
+  entry to 1st recv() (luckily causing Winsock to return ENOBUFS).
+
+  I've also added a ares_writev() for Windows to streamline the code a bit
+  more.
+
+* July 20
+- Fixed a few variable return types for some system calls. Made configure
+  check for ssize_t to make it possible to use that when receiving the send()
+  error code. This is necessary to prevent compiler warnings on some systems.
+
+- Made configure create config.h, and all source files now include setup.h that
+  might include the proper config.h (or a handicrafted alternative).
+
+- Switched to 'ares_socket_t' type for sockets in ares, since Windows don't
+  use 'int' for that.
+
+- automake-ified and libool-ified c-ares. Now it builds libcares as a shared
+  lib on most platforms if wanted. (This bloated the size of the release
+  archive with another 200K!)
+
+- Makefile.am now uses Makefile.inc for the c sources, h headers and man
+  pages, to make it easier for other makefiles to use the exact same set of
+  files.
+
+- Adjusted 'maketgz' to use the new automake magic when building distribution
+  archives.
+
+- Anyone desires HTML and/or PDF versions of the man pages in the release
+  archives?
+
+* July 3
+- G<>nter Knauf made c-ares build and run on Novell Netware.
+
+* July 1
+- Gisle Vanem provided Makefile.dj to build with djgpp, added a few more djgpp
+  fixes and made ares not use 'errno' to provide further info on Windows.
+
+* June 30
+- Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack.
+
+* June 10
+- Gisle Vanem's init patch for Windows:
+
+  The init_by_resolv_conf() function fetches the DNS-server(s)
+  from a series of registry branches.
+
+  This can be wrong in the case where DHCP has assigned nameservers, but the
+  user has overridden these servers with other prefered settings. Then it's
+  wrong to use the DHCPNAMESERVER setting in registry.
+
+  In the case of no global DHCP-assigned or fixed servers, but DNS server(s)
+  per adapter, one has to query the adapter branches.  But how can c-ares know
+  which adapter is valid for use? AFAICS it can't. There could be one adapter
+  that is down (e.g. a VPN adapter).
+
+  So it's better to leave this to the IP Helper API (iphlapi) available in
+  Win-98/2000 and later. My patch falls-back to the old way if not available.
+
+* June 8
+- James Bursa fixed an init issue for RISC OS.
+
+* May 11
+- Nico Stappenbelt reported that when processing domain and search lines in
+  the resolv.conf file, the first entry encountered is processed and used as
+  the search list. According to the manual pages for both Linux, Solaris and
+  Tru64, the last entry of either a domain or a search field is used.
+
+  This is now adjusted in the code
+
+Version 1.2.0 (April 13, 2004)
+
+* April 2, 2004
+- Updated various man pages to look nicer when converted to HTML on the web
+  site.
+
+* April 1, 2004
+- Dirk Manske provided a new function that is now named ares_cancel(). It is
+  used to cancel/cleanup a resolve/request made using ares functions on the
+  given ares channel. It does not destroy/kill the ares channel itself.
+
+- Dominick Meglio cleaned up the formatting in several man pages.
+
+* March 30, 2004
+- Dominick Meglio's new ares_expand_string. A helper function when decoding
+  incoming DNS packages.
+
+- Daniel Stenberg modified the Makefile.in to use a for loop for the man page
+  installation to improve overview and make it easier to add man pages.
+
+Version 1.1.0 (March 11, 2004)
+
+* March 9, 2004
+- Gisle Vanem improved build on Windows.
+
+* February 25, 2004
+- Dan Fandrich found a flaw in the Feb 22 fix.
+
+- Added better configure --enable-debug logic (taken from the curl configure
+  script). Added acinclude.m4 to the tarball.
+
+* February 23, 2004
+- Removed ares_free_errmem(), the function, the file and the man page. It was
+  not used and it did nothing.
+
+- Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of
+  compiler warnings on picky compilers.
+
+* February 22, 2004
+- Dominick Meglio made ares init support multiple name servers in the
+  NameServer key on Windows.
+
+* February 16, 2004
+- Modified ares_private.h to include libcurl's memory debug header if
+  CURLDEBUG is set. This makes all the ares-functions supervised properly by
+  the curl test suite. This also forced me to add inclusion of the
+  ares_private.h header in a few more files that are using some kind of
+  memory-related resources.
+
+- Made the makefile only build ahost and adig if 'make demos' is used.
+
+* February 10, 2004
+- Dirk Manske made ares_version.h installed with 'make install'
+
+* February 4, 2004
+- ares_free_errmem() is subject for removal, it is simply present for future
+  purposes, and since we removed the extra parameter in strerror() it won't
+  be used by c-ares!
+- configure --enable-debug now enables picky compiler options if gcc is used
+- fixed several compiler warnings --enable-debug showed and Joerg Mueller-Tolk
+  reported
+
+Version 1.0.0 (February 3, 2004)
+
+* February 3, 2004
+- now we produce the libcares.a library instead of the previous libares.a
+  since we are no longer compatible
+
+* February 2, 2004
+
+- ares_strerror() has one argument less. This is the first official
+  modification of the existing provided ares API.
+
+* January 29, 2004
+
+- Dirk Manske fixed how the socket is set non-blocking.
+
+* January 4, 2004
 
 - Dominick Meglio made the private gettimeofday() become ares_gettimeofday()
   instead in order to not pollute the name space and risk colliding with
   other libraries' versions of this function.

+c-ares
+======
+
+This package is based on ares 1.1.1 (written by Greg Hudson). I decided to
+fork and release a separate project since the ares author didn't want the
+improvements that were vital for our use of it.
+
+This package is dubbed 'c-ares' since I (Daniel Stenberg) wanted this for use
+within the curl project (hence the letter C) and it makes a nice pun. Also,
+c-ares is not API compatible with ares: a new name makes that more obvious to
+the public.
+
+The full source code is available in the 'c-ares' release archives, and in the
+'ares' subdir of the curl CVS source repostitory.
+
+If you find bugs, correct flaws, have questions or have comments in general in
+regard to c-ares (or by all means the original ares too), get in touch with us
+on the c-ares mailing list: http://cool.haxx.se/mailman/listinfo/c-ares
+
+c-ares is of course distributed under the same MIT-style license as the
+original ares.
+
+You'll find all c-ares details and news here:

-dnl This file provides local macros for packages which use specific
-dnl external libraries.  The public macros are:
-dnl
-dnl	ATHENA_UTIL_COM_ERR
-dnl		Generates error if com_err not found.
-dnl	ATHENA_UTIL_SS
-dnl		Generates error if ss not found.
-dnl	ATHENA_REGEXP
-dnl		Sets REGEX_LIBS if rx library used; ensures POSIX
-dnl		regexp support.
-dnl	ATHENA_MOTIF
-dnl		Sets MOTIF_LIBS and defines HAVE_MOTIF if Motif used.
-dnl	ATHENA_MOTIF_REQUIRED
-dnl		Generates error if Motif not found.
-dnl	ATHENA_AFS
-dnl		Sets AFS_LIBS and defines HAVE_AFS if AFS used.  Pass
-dnl		in an argument giving the desired AFS libraries;
-dnl		AFS_LIBS will be set to that value if AFS is found.
-dnl		AFS_DIR will be set to the prefix given.
-dnl	ATHENA_AFS_REQUIRED
-dnl		Generates error if AFS libraries not found.  AFS_DIR
-dnl		will be set to the prefix given.
-dnl	ATHENA_KRB4
-dnl		Sets KRB4_LIBS and defines HAVE_KRB4 if krb4 used.
-dnl	ATHENA_KRB4_REQUIRED
-dnl		Generates error if krb4 not found.  Sets KRB4_LIBS
-dnl		otherwise.  (Special behavior because krb4 libraries
-dnl		may be different if using krb4 compatibility libraries
-dnl		from krb5.)
-dnl	ATHENA_KRB5
-dnl		Sets KRB5_LIBS and defines HAVE_KRB5 if krb5 used.
-dnl	ATHENA_KRB5_REQUIRED
-dnl		Generates error if krb5 not found.
-dnl	ATHENA_HESIOD
-dnl		Sets HESIOD_LIBS and defines HAVE_HESIOD if Hesiod
-dnl		used.
-dnl	ATHENA_HESIOD_REQUIRED
-dnl		Generates error if Hesiod not found.
-dnl	ATHENA_ARES
-dnl		Sets ARES_LIBS and defines HAVE_ARES if libares
-dnl		used.
-dnl	ATHENA_ARES_REQUIRED
-dnl		Generates error if libares not found.
-dnl	ATHENA_ZEPHYR
-dnl		Sets ZEPHYR_LIBS and defines HAVE_ZEPHYR if zephyr
-dnl		used.
-dnl	ATHENA_ZEPHYR_REQUIRED
-dnl		Generates error if zephyr not found.
-dnl
-dnl All of the macros may extend CPPFLAGS and LDFLAGS to let the
-dnl compiler find the requested libraries.  Put ATHENA_UTIL_COM_ERR
-dnl and ATHENA_UTIL_SS before ATHENA_AFS or ATHENA_AFS_REQUIRED; there
-dnl is a com_err library in the AFS libraries which requires -lutil.

-ares_free_errmem \- Free memory allocated by ares_strerror

 .B #include <ares.h>
 .PP
-.B void ares_free_errmem(char *\fIerrmem\fP)
+.B int ares_cancel(ares_channel \fIchannel\fP)
 .fi
 .SH DESCRIPTION
-The
-.B ares_free_errmem
-function frees any memory which might have been allocated by the
-.BR ares_strerror (3)
-function.  The parameter
-.I errmem
-should be set to the variable pointed to by the
-.I memptr
-argument previously passed to
-.IR ares_strerror .
+The \fBares_cancel\fP function cancels all lookups/requests made on the the
+name service channel identified by \fIchannel\fP.  \fBares_cancel\fP invokes
+the callbacks for each pending query on the channel, passing a status of
+.BR ARES_ETIMEOUT .
+These calls give the callbacks a chance to clean up any state which
+might have been stored in their arguments.

+.SH NAME
+ares_expand_string \- Expand a length encoded string
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_expand_string(const unsigned char *\fIencoded\fP,
+.B      const unsigned char *\fIabuf\fP, int \fIalen\fP, unsigned char **\fIs\fP,
+.B 	int *\fIenclen\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_expand_string
+function converts a length encoded string to a NULL terminated C
+string.  The argument
+.I encoded
+gives the beginning of the encoded string, and the arguments
+.I abuf
+and
+.I alen
+give the containing message buffer (necessary for the processing of
+indirection pointers within the encoded domain name).  The result is
+placed in a NUL-terminated allocated buffer, a pointer to which is
+stored in the variable pointed to by
+.IR s .
+The length of the encoded string is stored in the variable pointed to by
+.I enclen
+so that the caller can advance past the encoded string to read
+further data in the message.
+.SH RETURN VALUES
+.B ares_expand_string
+can return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+Expansion of the encoded string succeeded.
+.TP 15
+.B ARES_EBADSTR
+The encoded string was malformed and could not be expanded.
+.TP 15
+.B ARES_ENOMEM
+Memory was exhausted.

+.nf
+.B #include <ares.h>
+.PP
+.B const char *ares_version(int *\fIversion\fP)

+.SH DESCRIPTION
+The
+.B ares_version
+function gets the library version as a string and optionally as an integer
+stored in the
+.IR version ,
+argument. If you pass a NULL, no integer is attempted to be returned.
+
+The integer is built up as 24bit number, with 8 separate bits used for major
+number, minor number and patch number. This makes a version string such as
+1.2.3 will be returned as the hexadecimal number 0x010203 (decimal 66051).

+  3.16 What certificates do I need when I use SSL?
+
+  There are three different kinds of "certificates" to keep track of when we
+  talk about using SSL-based protocols (HTTPS or FTPS) using curl or libcurl.
+
+  - Client certificate. The server you communicate may require that you can
+    provide this in order to prove that you actually are who you claim to be.
+    If the server doesn't require this, you don't need a client certificate.
+
+  - Server certificate. The server you communicate with has a server
+    certificate. You can and should verify this certficate to make sure that
+    you are truly talking to the real server and not a server impersonating
+    it. The server certificate verifaction process is made by using a
+    Certificate Authority certificate ("CA cert") that was used to sign the
+    server certificate. Server certificate verification is enabled by default
+    in curl and libcurl and is often the reason for problems as explained in
+    FAQ entry 4.12 and the SSLCERTS document
+    (http://curl.haxx.se/docs/sslcerts.html). Server certificates that are
+    "self-signed" or otherwise signed by a CA that you do not have a CA cert
+    for, cannot be verified. If the verification during a connect fails, you
+    are refused access. You then need to explicitly disable the verification
+    to connect to the server.
+
+  - Certificate Authority certificate ("CA cert"). You often have several CA
+    certs in a CA cert bundle that can be used to verify a server certificate
+    that was signed by one of the authorities in the bundle. curl comes with a
+    default CA cert bundle. You can override the default.

-Single Threaded Re-Entracy
---------------------------
-
-There is a glitch / trick to using cURL on Win32 related to re-entrancy.
-This experience was gained on verion 7.9.4 using Windows NT SP3 in a banking
-environment (just in case you wanted to know).
-
-If you have already called curl_easy_perform(), and *somehow* you cause your
-single thread of execution to make another call to curl_easy_perform() - the
-windows socket() call used to create a new socket for the second connection
-can return with 10044 / 10043 error codes.
-
-The WSA errors we experienced are:
-WSAEPROTONOSUPPORT 
-(10043) 
-Protocol not supported. 
-The requested protocol has not been configured into the system, or no
-implementation for it exists. For example, a socket call requests a
-SOCK_DGRAM socket, but specifies a stream protocol. 
-
-WSAESOCKTNOSUPPORT 
-(10044) 
-Socket type not supported. 
-The support for the specified socket type does not exist in this address
-family. For example, the optional type SOCK_RAW might be selected in a
-socket call, and the implementation does not support SOCK_RAW sockets at
-all. 
-
-We have experienced this by creating a timer that ticks every 20ms, and on
-the tick making a curl_easy_perform() call.  The call usually completed in
-about 300ms.  And we expected (before this test) that the timer would NOT be
-fired during a call to curl_easy_perform(), howvever, while the first
-curl_easy_perform() is running a tick *is* fired by the windows API somehow,
-and we then call curl_easy_perform() again - thus single threaded
-re-entrancy is achieved.
-
-Notes:
-* We made sure that a new CURL structure was being used for each
-curl_easy_perform() request, and that the curl_global_init() had been called
-beforehand.  
-* I'm happy to answer any questions about this problem to try to track it
-down.
-* Once the socket() call started failing, there is no hope - it never works
-again.
-* Slowing the timer down to give each request enough time to complete solves
-this problem completely.
-
-If anyone has the source code to the WinNT implementation of socket() and
-can figure out WHY this can occur, more tracing can be performed.

+         License Mixing with apps, libcurl and Third Party Libraries
+         ===========================================================
+
+libcurl can be built to use a fair amount of various third party libraries,
+libraries that are written and provided by other parties that are distributed
+using their own licenses. Even libcurl itself contains code that may cause
+problems to some. This document attempts to describe what licenses libcurl and
+the other libraries use and what possible dilemmas linking and mixing them all
+can lead to for end users.
+
+I am not a lawyer and this is not legal advice!
+
+One common dilemma is that GPL[1]-licensed code is not allowed to be linked
+with code licensed under the Original BSD license (with the announcement
+clause, unless there's a specified exception in the GPL-licensed module). You
+may still build your own copies that use them all, but distributing them as
+binaries would be to violate the GPL license - unless you accompany your
+license with an exception[2]. This particular problem was addressed when the
+Modified BSD license was created, which does not have the annoncement clause
+that collides with GPL.
+
+libcurl http://curl.haxx.se/docs/copyright.html
+
+        Uses an MIT (or Modified BSD)-style license that is as liberal as
+        possible.  Some of the source files that deal with KRB4 have Original
+        BSD-style announce-clause licenses. You may not distribute binaries
+        with krb4-enabled libcurl that also link with GPL-licensed code!
+
+OpenSSL http://www.openssl.org/source/license.html
+
+        Uses an Original BSD-style license with an announement clause that
+        makes it "incompatible" with GPL. You are not allowed to ship binaries
+        that link with OpenSSL that includes GPL code (unless that specific
+        GPL code includes an exception for OpenSSL - a habit that is growing
+        more and more common).
+
+c-ares  http://daniel.haxx.se/projects/c-ares/license.html
+
+        Uses an MIT license that is very liberal and imposes no restrictions
+        on any other library or part you may link with.
+
+zlib    http://www.gzip.org/zlib/zlib_license.html
+
+        Uses an MIT-style license that shouldn't collide with any other
+        library.
+
+krb4
+
+        While nothing in particular says that a Kerberos4 library must use any
+        particular license, the one I've tried and used successfully so far
+        (kth-krb4) is Original BSD-licensed with the announcement clause. Some
+        of the code in libcurl that is written to deal with Kerberos4 likewise
+        have such a license.
+
+GSSAPI
+
+        While nothing in particular says that a GSS/Kerberos5 library must use
+        any particular license, the one I've used (Heimdal) is Original BSD-
+        licensed with the announcement clause.
+
+fbopenssl
+
+        Unclear license. Based on its name, I assume that it uses the OpenSSL
+        license and thus shares the same issues as described for OpenSSL
+        above.
+
+libidn  http://www.gnu.org/licenses/lgpl.html
+
+        Uses the GNU Lesser General Public License. LGPL is a variation of GPL
+        with slightly less aggressive "copyleft". This license requires more
+        requirements to be met when distributing binaries, see the license for
+        details. Also note that if you distribute a binary that includes this
+        library, you must also include the full LGPL license text. Please
+        properly point out what parts of the distributed package that the
+        license addresses.
+
+OpenLDAP http://www.openldap.org/software/release/license.html
+
+        Uses a Modified BSD-style license. Since libcurl uses OpenLDAP as a

+  Curl has been successfully compiled with gcc / nlmconv on different flavours
+  of Linux as well as with the official Metrowerks CodeWarrior compiler.
+  While not being the main development target, a continously growing share of 
+  curl users are NetWare-based, specially also consuming the lib from PHP.
+      
+  The unix-style man pages are tricky to read on windows, so therefore are all
+  those pages converted to HTML as well as pdf, and included in the release
+  archives.
+
+  The main curl.1 man page is also "built-in" in the command line tool. Use a
+  command line similar to this in order to extract a separate text file:
+
+        curl -M >manual.txt
+
+  Read the INSTALL file for instructions how to compile curl self.

                       Peer SSL Certificate Verification
                       =================================
 
-Starting in 7.10, libcurl performs peer SSL certificate verification by
-default. This is done by installing a default CA cert bundle on 'make install'
-(or similar), that CA bundle package is used by default on operations against
-SSL servers.

-Alas, if you communicate with HTTPS servers using certificates that are signed
-by CAs present in the bundle, you will not notice any changed behavior and you
-will seamlessly get a higher security level on your SSL connections since you
-can be sure that the remote server really is the one it claims to be.
+If you communicate with HTTPS or FTPS servers using certificates that are

+really is the one it claims to be.
 
-If the remote server uses a self-signed certificate, or if you don't install
-curl's CA cert bundle or if it uses a certificate signed by a CA that isn't
-included in the bundle, then you need to do one of the following:

+impersonating your favorite site, and you want to transfer files from this
+server, do one of the following:
 
  1. Tell libcurl to *not* verify the peer. With libcurl you disable with with
     curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, FALSE);
 
-    With the curl command tool, you disable this with -k/--insecure.
+    With the curl command line tool, you disable this with -k/--insecure.
 
  2. Get a CA certificate that can verify the remote server and use the proper
     option to point out this CA cert for verification when connecting. For
     libcurl hackers: curl_easy_setopt(curl, CURLOPT_CAPATH, capath);
 
-    With the curl command tool: --cacert [file]
+    With the curl command line tool: --cacert [file]
 
-Neglecting to use one of the above menthods when dealing with a server using a
-certficate that isn't signed by one of the certficates in the installed CA
+ 3. Add the CA cert for your server to the existing default CA cert bundle.
+    The default path of the CA bundle installed with the curl package is:
+    /usr/local/share/curl/curl-ca-bundle.crt, which can be changed by running
+    configure with the --with-ca-bundle option pointing out the path of your
+    choice.
+
+    To do this, you need to get the CA cert for your server in PEM format and
+    then append that to your CA cert bundle.
+
+    If you use Internet Explorer, this is one way to get extract the CA cert
+    for a particular server:
+
+     o View the certificate by double-clicking the padlock
+     o Find out where the CA certificate is kept (Certificate>
+       Authority Information Access>URL)
+     o Get a copy of the crt file using curl
+     o Convert it from crt to PEM using the openssl tool:
+       openssl x509 -inform DES -in yourdownloaded.crt \
+       -out outcert.pem -text
+     o Append the 'outcert.pem' to the CA cert bundle or use it stand-alone
+       as described below.
+
+     (Thanks to Frankie V for this description)
+
+    If you use the 'openssl' tool, this is one way to get extract the CA cert
+    for a particular server:
+
+     o openssl s_client -connect xxxxx.com:443 |tee logfile
+     o type "QUIT", followed by the "ENTER" key
+     o The certificate will have "BEGIN CERTIFICATE" and "END CERTIFICATE"
+       markers.
+     o If you want to see the data in the certificate, you can do: "openssl
+       x509 -inform PEM -in certfile -text -out certdata" where certfile is
+       the cert you extracted from logfile. Look in certdata.
+     o If you want to trust the certificate, you can append it to your
+       cert_bundle or use it stand-alone as described. Just remember that the
+       security is no better than the way you obtained the certificate.
+
+     (Thanks to Doug Kaufman for this description)
+
+ 4. If you're using the curl command line tool, you can specify your own CA
+    cert path by setting the environment variable CURL_CA_BUNDLE to the path
+    of your choice.
+
+    If you're using the curl command line tool on Windows, curl will search
+    for a CA cert file named "curl-ca-bundle.crt" in these directories and in
+    this order:
+      1. application's directory
+      2. current working directory
+      3. Windows System directory (e.g. C:\windows\system32)
+      4. Windows Directory (e.g. C:\windows)
+      5. all directories along %PATH%
+
+ 5. Get a better/different/newer CA cert bundle! One option is to extract the
+    one a recent Mozilla browser uses, by following the instruction found
+    here:
+
+        http://curl.haxx.se/docs/caextract.html
+
+Neglecting to use one of the above methods when dealing with a server using a
+certificate that isn't signed by one of the certificates in the installed CA
 cert bundle, will cause SSL to report an error ("certificate verify failed")
 during the handshake and SSL will then refuse further communication with that
 server.

-This procedure has been deemed The Right Thing even though it adds this extra
-trouble for some users, since it adds security to a majority of the SSL
-connections that previously weren't really secure. It turned out many people
-were using previous versions of curl/libcurl without realizing the need for
-the CA cert options to get truly secure SSL connections.
