+# Add full (4 or 5 libs) SSL support
+# Add INSTALL target (EXTRA_DIST variables in Makefile.am may be moved to Makefile.inc so that CMake/CPack is aware of what's to include).

+# Check on all possible platforms

+# Create scripts that help keeping the CMake build system up to date (to reduce maintenance). According to Tetetest:
+#  - lists of headers that 'configure' checks for;
+#  - curl-specific tests (the ones that are in m4/curl-*.m4 files);
+#  - (most obvious thing:) curl version numbers.
+# Add documentation subproject
+#
+# To check:
+# (From Daniel Stenberg) The cmake build selected to run gcc with -fPIC on my box while the plain configure script did not.
+# (From Daniel Stenberg) The gcc command line use neither -g nor any -O options. As a developer, I also treasure our configure scripts's --enable-debug option that sets a long range of "picky" compiler options.

 This release includes the following changes:
 
- o 
+ o libcurl now closes all dead connections whenever you attempt to open a new

+ o curl can now upload with resume even when reading from a pipe
+ o a build-time configured curl_socklen_t is now used instead of socklen_t
 
 This release includes the following bugfixes:
 
- o build failure when using MSVC 6 makefile and on four platforms more
- o crash when using --interface name on Linux systems with a TEQL device
- o using the multi interface to download a HTTPS page with libcurl built
-   powered by OpenSSL could download "rubbish" instead of actual content
+ o NTLM authentication memory leak on SSPI enabled Windows builds
+ o fixed the GnuTLS-using code to do correct return code checks
+ o an alloc-related call in the OpenSSL-using code didn't check the return value
+ o curl_easy_duphandle() failed to duplicate cookies at times
+ o missing TELNET timeout support in Windows builds
+ o missing Curl_read() and write callback result checking in TELNET transfers
+ o more ciphers enabled in libcurl built to use NSS

   Changelog for the c-ares project
 
+* May 11 2009 (Daniel Stenberg)
+- Gregor Jasny made c-ares link with libtool 's -export-symbols-regex option to
+  only expose functions starting with ares_.
+
+* May 2 2009 (Yang Tse)
+- Use a build-time configured ares_socklen_t data type instead of socklen_t.
+
+* April 21 2009 (Yang Tse)
+- Moved potential inclusion of system's malloc.h and memory.h header files to
+  setup_once.h.  Inclusion of each header file is based on the definition of
+  NEED_MALLOC_H and NEED_MEMORY_H respectively.
+
+* March 11 2009 (Yang Tse)
+- Japheth Cleaver fixed acountry.c replacing u_long with unsigned long.
+
+* February 20 2009 (Yang Tse)
+- Do not halt compilation when using VS2008 to build a Windows 2000 target.
+
+* February 3 2009 (Phil Blundell)
+- If the server returns garbage or nothing at all in response to an AAAA query,
+  go on and ask for A records anyway.
+
+* January 31 2009 (Daniel Stenberg)
+- ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving
+  either AF_INET6 or AF_INET. It works by accepting any of the looksups in the
+  hosts file, and it resolves the AAAA field with a fallback to A.
+
+* January 14 2009 (Daniel Stenberg)
+- ares.h no longer uses the HAVE_STRUCT_IN6_ADDR define check, but instead it
+  now declares the private struct ares_in6_addr for all systems instead of
+  relying on one possibly not present in the system.
+
+* January 13 2009 (Phil Blundell)
+- ares__send_query() now varies the retry timeout pseudo-randomly to avoid
+  packet storms when several queries were started at the same time.
+
+* January 11 2009 (Daniel Stenberg)
+- Phil Blundell added the internal function ares__expand_name_for_response()
+  that is now used by the ares_parse_*_reply() functions instead of the
+  ares_expand_name() simply to easier return ARES_EBADRESP for the cases where
+  the name expansion fails as in responses that really isn't expected.
+
+Version 1.6.0 (Dec 9, 2008)
+
+* December 9 2008 (Gisle Vanem)
+
+  Fixes for Win32 targets using the Watt-32 tcp/ip stack.
+
+* Dec 4 2008 (Daniel Stenberg)
+
+  Gregor Jasny provided the patch that introduces ares_set_socket_callback(),
+  and I edited it to also get duped by ares_dup().
+
+* Dec 3 2008 (Daniel Stenberg)
+
+  API changes:
+
+  I made sure the public ares_config struct looks like before and yet it
+  supports the ROTATE option thanks to c-ares now storing the "optmask"
+  internally. Thus we should be ABI compatible with the past release(s)
+  now. My efforts mentioned below should not break backwards ABI compliance.
+
+  Here's how I suggest we proceed with the API:
+
+  ares_init() will be primary "channel creator" function.
+
+  ares_init_options() will continue to work exactly like now and before. For
+  starters, it will be the (only) way to set the existing options.
+
+  ares_save_options() will continue to work like today, but will ONLY save
+  options that you can set today (including ARES_OPT_ROTATE actually) but new
+  options that we add may not be saved with this.
+
+  Instead we introduce:
+
+  ares_dup() that instead can make a new channel and clone the config used
+  from an existing channel. It will then clone all config options, including
+  future new things we add.
+
+  ares_set_*() style functions that set (new) config options. As a start we
+  simply add these for new functionality, but over time we can also introduce
+  them for existing "struct ares_options" so that we can eventually deprecate
+  the two ares_*_options() functions.
+
+  ares_get_*() style functions for extracting info from a channel handle that
+  should be used instead of ares_save_options().
+
+* Nov 26 2008 (Yang Tse)
+- Brad Spencer provided changes to allow buildconf to work on OS X.
+
+- Gerald Combs fixed a bug in ares_parse_ptr_reply() which would cause a
+  buffer to shrink instead of expand if a reply contained 8 or more records.
+
+* Nov 25 2008 (Yang Tse)
+- In preparation for the upcomming IPv6 nameservers patch, the internal
+  ares_addr union is now changed into an internal struct which also holds
+  the address family.
+
+* Nov 19 2008 (Daniel Stenberg)
+- Brad Spencer brought the new function ares_gethostbyname_file() which simply
+  resolves a host name from the given file, using the regular hosts syntax.
+
 * Nov 1 2008 (Daniel Stenberg)
 - Carlo Contavalli added support for the glibc "rotate" option, as documented
-  in man resolv.conf: 
+  in man resolv.conf:
 
   causes round robin selection of nameservers from among those listed.  This
   has the effect of spreading the query load among all listed servers, rather

+NOTES FOR C-ARES HACKERS
+
+The following notes apply to c-ares version 1.6.1 and later.
+
+* The distributed ares_build.h file is only intended to be used on systems
+  which can not run the also distributed configure script.
+
+* The distributed ares_build.h file is generated as a copy of ares_build.h.dist
+  when the c-ares source code distribution archive file is originally created.
+
+* If you check out from CVS on a non-configure platform, you must run the
+  appropriate buildconf* script to set up ares_build.h and other local files
+  before being able of compiling the library.
+
+* On systems capable of running the configure script, the configure process
+  will overwrite the distributed ares_build.h file with one that is suitable
+  and specific to the library being configured and built, this new file is
+  generated from the ares_build.h.in template file.
+
+* If you intend to distribute an already compiled c-ares library you _MUST_
+  also distribute along with it the generated ares_build.h which has been
+  used to compile it. Otherwise the library will be of no use for the users of
+  the library that you have built. It is _your_ responsability to provide this
+  file. No one at the c-ares project can know how you have built the library.
+
+* File ares_build.h includes platform and configuration dependant info,
+  and must not be modified by anyone. Configure script generates it for you.
+
+* We cannot assume anything else but very basic compiler features being
+  present. While c-ares requires an ANSI C compiler to build, some of the
+  earlier ANSI compilers clearly can't deal with some preprocessor operators.
+
+* Newlines must remain unix-style for older compilers' sake.
+
+* Comments must be written in the old-style /* unnested C-fashion */
+

- o improved configure detection of several functions
- o improved source code portability
+Changed:
+
+ o in6_addr is not used in ares.h anymore, but a private ares_in6_addr is
+   instead declared and used
+ o ares_gethostbyname() now supports 'AF_UNSPEC' as a family for resolving

+.TH ARES_DUP 3 "2 Dec 2008"
+.SH NAME
+ares_dup \- Duplicate a resolver channel
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_dup(ares_channel *\fIchannel\fP, ares_channel \fIsource\fP)
+.fi
+.SH DESCRIPTION
+The \fBares_dup(3)\fP function duplicates an existing communications channel
+for name service lookups.  If it returns successfully, \fBares_dup(3)\fP will
+set the variable pointed to by \fIchannel\fP to a handle used to identify the
+name service channel.  The caller should invoke \fIares_destroy(3)\fP on the
+handle when the channel is no longer needed.
+
+The \fBares_dup_options\fP function also initializes a name service channel,
+with additional options set exactly as the \fIsource\fP channel has them
+configured.
+.SH SEE ALSO
+.BR ares_destroy(3),
+.BR ares_init(3)
+.SH AVAILABILITY
+ares_dup(3) was added in c-ares 1.6.0

+.SH NAME
+ares_gethostbyname_file \- Lookup a name in the system's hosts file
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B void ares_gethostbyname_file(ares_channel \fIchannel\fP, const char *\fIname\fP,
+.B 	int \fIfamily\fP, struct hostent **host)
+.fi
+.SH DESCRIPTION
+The
+.B ares_gethostbyname_file
+function performs a host lookup by name against the system's hosts file (or equivalent local hostname database).  
+The
+.IR channel
+parameter is required, but no asynchronous queries are performed.  Instead, the
+lookup is done via the same mechanism used to perform 'f' lookups
+(see the
+.I lookups
+options field in \fIares_init_options(3)\fP).
+The parameter
+.I name
+gives the hostname as a NUL-terminated C string, and
+.I family
+gives the desired type of address for the resulting host entry.  
+.PP
+The return value indicates whether the query succeeded and, if not, how it
+failed.  It may have any of the following values:
+.TP 19
+.B ARES_SUCCESS
+The host lookup completed successfully and 
+.I host
+now points to the result (and must be freed with \fIares_free_hostent(3)\fP).
+.TP 19
+.B ARES_ENOTFOUND
+The hostname
+.I name
+was not found.
+.TP 19
+.B ARES_EFILE
+There was a file I/O error while performing the lookup.
+.TP 19
+.B ARES_ENOMEM
+Memory was exhausted.
+.PP
+On successful completion of the query, the pointer pointed to by
+.I host
+points to a
+.B struct hostent
+containing the address of the host returned by the lookup.  The user must
+free the memory pointed to by
+.IR host
+when finished with it by calling \fIares_free_hostent(3)\fP.  If the lookup did
+not complete successfully, 
+.I host
+will be
+.BR NULL .
+.SH AVAILABILITY
+Added in c-ares 1.5.4

+/*
+ * NOTE 1:
+ * -------
+ *
+ * All checks done in this file are intentionally placed in a public
+ * header file which is pulled by ares.h when an application is
+ * being built using an already built c-ares library. Additionally
+ * this file is also included and used when building the library.
+ *
+ * If compilation fails on this file it is certainly sure that the
+ * problem is elsewhere. It could be a problem in the ares_build.h
+ * header file, or simply that you are using different compilation
+ * settings than those used to build the library.
+ *
+ * Nothing in this file is intended to be modified or adjusted by the
+ * c-ares library user nor by the c-ares library builder.
+ *
+ * Do not deactivate any check, these are done to make sure that the
+ * library is properly built and used.
+ *
+ * You can find further help on the c-ares development mailing list:
+ * http://cool.haxx.se/mailman/listinfo/c-ares/
+ *
+ * NOTE 2
+ * ------
+ *
+ * Some of the following compile time checks are based on the fact
+ * that the dimension of a constant array can not be a negative one.
+ * In this way if the compile time verification fails, the compilation
+ * will fail issuing an error. The error description wording is compiler
+ * dependant but it will be quite similar to one of the following:
+ *
+ *   "negative subscript or subscript is too large"
+ *   "array must have at least one element"
+ *   "-1 is an illegal array size"
+ *   "size of array is negative"
+ *
+ * If you are building an application which tries to use an already
+ * built c-ares library and you are getting this kind of errors on
+ * this file, it is a clear indication that there is a mismatch between
+ * how the library was built and how you are trying to use it for your
+ * application. Your already compiled or binary library provider is the
+ * only one who can give you the details you need to properly use it.
