+# curl/libcurl CMake script
+# by Tetetest and Sukender (Benoit Neil)
+
+# TODO:
+# The output .so file lacks the soname number which we currently have within the lib/Makefile.am file
+# 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).
+# Add CTests(?)
+# Check on all possible platforms
+# Test with as many configurations possible (With or without any option)
+# 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.

+README
+
+  Curl is a command line tool for transferring data specified with URL
+  syntax. Find out how to use curl by reading the curl.1 man page or the
+  MANUAL document. Find out how to install Curl by reading the INSTALL
+  document.
+
+  libcurl is the library curl is using to do its job. It is readily
+  available to be used by your software. Read the libcurl.3 man page to
+  learn how!
+
+  You find answers to the most frequent questions we get in the FAQ document.
+
+  Study the COPYING file for distribution terms and similar. If you distribute
+  curl binaries or other binaries that involve libcurl, you might enjoy the
+  LICENSE-MIXING document.
+
+CONTACT
+
+  If you have problems, questions, ideas or suggestions, please contact us
+  by posting to a suitable mailing list. See https://curl.haxx.se/mail/
+
+  All contributors to the project are listed in the THANKS document.

+Include files for libcurl, external users.
+
+They're all placed in the curl subdirectory here for better fit in any kind
+of environment. You must include files from here using...
+
+        #include <curl/curl.h>
+
+... style and point the compiler's include path to the directory holding the
+curl subdirectory. It makes it more likely to survive future modifications.
+
+NOTE FOR LIBCURL HACKERS
+
+* If you check out from git on a non-configure platform, you must run the
+  appropriate buildconf* script to set up files before being able of compiling
+  the library.
+
+* We cannot assume anything else but very basic compiler features being
+  present. While libcurl 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 */
+
+To figure out how to do good and portable checks for features, operating
+systems or specific hardwarare, a very good resource is Bjorn Reese's
+collection at https://sourceforge.net/p/predef/wiki/

+ * Try to keep one section per platform, compiler and architecture, otherwise,
+ * if an existing section is reused for a different one and later on the

+ * curl_off_t
+ * ----------
+ *
+ * For any given platform/compiler curl_off_t must be typedef'ed to a 64-bit
+ * wide signed integral data type. The width of this data type must remain
+ * constant and independent of any possible large file support settings.
+ *
+ * As an exception to the above, curl_off_t shall be typedef'ed to a 32-bit
+ * wide signed integral data type if there is no 64-bit type.
+ *
+ * As a general rule, curl_off_t shall not be mapped to off_t. This rule shall
+ * only be violated if off_t is the only 64-bit data type available and the
+ * size of off_t is independent of large file support settings. Keep your
+ * build on the safe side avoiding an off_t gating.  If you have a 64-bit
+ * off_t then take for sure that another 64-bit data type exists, dig deeper
+ * and you will find it.

+============================
+
+struct CookieInfo *Curl_cookie_init(struct Curl_easy *data,
+                    const char *file, struct CookieInfo *inc, bool newsession);
+
+        Inits a cookie struct to store data in a local file. This is always
+        called before any cookies are set.
+
+struct Cookie *Curl_cookie_add(struct Curl_easy *data,
+                 struct CookieInfo *c, bool httpheader, char *lineptr,
+                 const char *domain, const char *path);
+
+        The 'lineptr' parameter is a full "Set-cookie:" line as
+        received from a server.
+
+        The function need to replace previously stored lines that this new
+        line superceeds.
+
+        It may remove lines that are expired.
+
+        It should return an indication of success/error.
+
+
+SENDING COOKIE INFORMATION
+==========================
+
+struct Cookies *Curl_cookie_getlist(struct CookieInfo *cookie,
+                                    char *host, char *path, bool secure);
+
+        For a given host and path, return a linked list of cookies that
+        the client should send to the server if used now. The secure
+        boolean informs the cookie if a secure connection is achieved or
+        not.
+
+        It shall only return cookies that haven't expired.
+
+
+Example set of cookies:
+
+    Set-cookie: PRODUCTINFO=webxpress; domain=.fidelity.com; path=/; secure
+    Set-cookie: PERSONALIZE=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
+    domain=.fidelity.com; path=/ftgw; secure
+    Set-cookie: FidHist=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
+    domain=.fidelity.com; path=/; secure
+    Set-cookie: FidOrder=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
+    domain=.fidelity.com; path=/; secure
+    Set-cookie: DisPend=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;

+ * Nasty internal details ahead...
+ *
+ * File curl_memory.h must be included by _all_ *.c source files
+ * that use memory related functions strdup, malloc, calloc, realloc
+ * or free, and given source file is used to build libcurl library.
+ * It should be included immediately before memdebug.h as the last files
+ * included to avoid undesired interaction with other memory function
+ * headers in dependent libraries.
+ *
+ * There is nearly no exception to above rule. All libcurl source
+ * files in 'lib' subdirectory as well as those living deep inside
+ * 'packages' subdirectories and linked together in order to build
+ * libcurl library shall follow it.
+ *
+ * File lib/strdup.c is an exception, given that it provides a strdup
+ * clone implementation while using malloc. Extra care needed inside
+ * this one. TODO: revisit this paragraph and related code.
+ *
+ * The need for curl_memory.h inclusion is due to libcurl's feature
+ * of allowing library user to provide memory replacement functions,
+ * memory callbacks, at runtime with curl_global_init_mem()
+ *
+ * Any *.c source file used to build libcurl library that does not
+ * include curl_memory.h and uses any memory function of the five
+ * mentioned above will compile without any indication, but it will
+ * trigger weird memory related issues at runtime.
+ *
+ * OTOH some source files from 'lib' subdirectory may additionally be
+ * used directly as source code when using some curlx_ functions by
+ * third party programs that don't even use libcurl at all. When using
+ * these source files in this way it is necessary these are compiled
+ * with CURLX_NO_MEMORY_CALLBACKS defined, in order to ensure that no
+ * attempt of calling libcurl's memory callbacks is done from code
+ * which can not use this machinery.
+ *
+ * Notice that libcurl's 'memory tracking' system works chaining into
+ * the memory callback machinery. This implies that when compiling
+ * 'lib' source files with CURLX_NO_MEMORY_CALLBACKS defined this file
+ * disengages usage of libcurl's 'memory tracking' system, defining
+ * MEMDEBUG_NODEFINES and overriding CURLDEBUG purpose.
+ *
+ * CURLX_NO_MEMORY_CALLBACKS takes precedence over CURLDEBUG. This is
+ * done in order to allow building a 'memory tracking' enabled libcurl
+ * and at the same time allow building programs which do not use it.
+ *
+ * Programs and libraries in 'tests' subdirectories have specific
+ * purposes and needs, and as such each one will use whatever fits
+ * best, depending additionally whether it links with libcurl or not.
+ *
+ * Caveat emptor. Proper curlx_* separation is a work in progress
+ * the same as CURLX_NO_MEMORY_CALLBACKS usage, some adjustments may
+ * still be required. IOW don't use them yet, there are sharp edges.
