+Catch
+-----
+
+This module defines a function to help use the Catch test framework.
+
+The :command:`catch_discover_tests` discovers tests by asking the compiled test
+executable to enumerate its tests.  This does not require CMake to be re-run
+when tests change.  However, it may not work in a cross-compiling environment,
+and setting test properties is less convenient.
+
+This command is intended to replace use of :command:`add_test` to register
+tests, and will create a separate CTest test for each Catch test case.  Note
+that this is in some cases less efficient, as common set-up and tear-down logic
+cannot be shared by multiple test cases executing in the same instance.
+However, it provides more fine-grained pass/fail information to CTest, which is
+usually considered as more beneficial.  By default, the CTest test name is the
+same as the Catch name; see also ``TEST_PREFIX`` and ``TEST_SUFFIX``.
+
+.. command:: catch_discover_tests
+
+  Automatically add tests with CTest by querying the compiled test executable
+  for available tests::
+
+    catch_discover_tests(target
+                         [TEST_SPEC arg1...]
+                         [EXTRA_ARGS arg1...]
+                         [WORKING_DIRECTORY dir]
+                         [TEST_PREFIX prefix]
+                         [TEST_SUFFIX suffix]
+                         [PROPERTIES name1 value1...]
+                         [TEST_LIST var]
+    )
+
+  ``catch_discover_tests`` sets up a post-build command on the test executable
+  that generates the list of tests by parsing the output from running the test
+  with the ``--list-test-names-only`` argument.  This ensures that the full
+  list of tests is obtained.  Since test discovery occurs at build time, it is
+  not necessary to re-run CMake when the list of tests changes.
+  However, it requires that :prop_tgt:`CROSSCOMPILING_EMULATOR` is properly set
+  in order to function in a cross-compiling environment.
+
+  Additionally, setting properties on tests is somewhat less convenient, since
+  the tests are not available at CMake time.  Additional test properties may be
+  assigned to the set of tests as a whole using the ``PROPERTIES`` option.  If
+  more fine-grained test control is needed, custom content may be provided
+  through an external CTest script using the :prop_dir:`TEST_INCLUDE_FILES`
+  directory property.  The set of discovered tests is made accessible to such a
+  script via the ``<target>_TESTS`` variable.
+
+  The options are:
+
+  ``target``
+    Specifies the Catch executable, which must be a known CMake executable
+    target.  CMake will substitute the location of the built executable when
+    running the test.
+
+  ``TEST_SPEC arg1...``
+    Specifies test cases, wildcarded test cases, tags and tag expressions to
+    pass to the Catch executable with the ``--list-test-names-only`` argument.
+
+  ``EXTRA_ARGS arg1...``
+    Any extra arguments to pass on the command line to each test case.
+
+  ``WORKING_DIRECTORY dir``
+    Specifies the directory in which to run the discovered test cases.  If this
+    option is not provided, the current binary directory is used.
+
+  ``TEST_PREFIX prefix``
+    Specifies a ``prefix`` to be prepended to the name of each discovered test
+    case.  This can be useful when the same test executable is being used in
+    multiple calls to ``catch_discover_tests()`` but with different
+    ``TEST_SPEC`` or ``EXTRA_ARGS``.
+
+  ``TEST_SUFFIX suffix``
+    Similar to ``TEST_PREFIX`` except the ``suffix`` is appended to the name of
+    every discovered test case.  Both ``TEST_PREFIX`` and ``TEST_SUFFIX`` may
+    be specified.
+
+  ``PROPERTIES name1 value1...``
+    Specifies additional properties to be set on all tests discovered by this
+    invocation of ``catch_discover_tests``.
+
+  ``TEST_LIST var``
+    Make the list of tests available in the variable ``var``, rather than the
+    default ``<target>_TESTS``.  This can be useful when the same test
+    executable is being used in multiple calls to ``catch_discover_tests()``.
+    Note that this variable is only available in CTest.

 ## Built in matchers
-Currently Catch has some string matchers and some vector matchers. They are in the `Catch::Matchers` and `Catch` namespaces.
-The string matchers are `StartsWith`, `EndsWith`, `Contains` and `Equals`. Each of them also takes an optional second argument, that decides case sensitivity (by-default, they are case sensitive).
+Catch currently provides some matchers, they are in the `Catch::Matchers` and `Catch` namespaces.
+
+### String matchers
+The string matchers are `StartsWith`, `EndsWith`, `Contains`, `Equals` and `Matches`. The first four match a literal (sub)string against a result, while `Matches` takes and matches an ECMAScript regex. Do note that `Matches` matches the string as a whole, meaning that "abc" will not match against "abcd", but "abc.*" will.
+
+Each of the provided `std::string` matchers also takes an optional second argument, that decides case sensitivity (by-default, they are case sensitive).
+
+
+### Vector matchers
 The vector matchers are `Contains`, `VectorContains` and `Equals`. `VectorContains` looks for a single element in the matched vector, `Contains` looks for a set (vector) of elements inside the matched vector.
 
+### Floating point matchers
+The floating point matchers are `WithinULP` and `WithinAbs`. `WithinAbs` accepts floating point numbers that are within a certain margin of target. `WithinULP` performs an [ULP](https://en.wikipedia.org/wiki/Unit_in_the_last_place)-based comparison of two floating point numbers and accepts them if they are less than certain number of ULPs apart.
+
+Do note that ULP-based checks only make sense when both compared numbers are of the same type and `WithinULP` will use type of its argument as the target type. This means that `WithinULP(1.f, 1)` will expect to compare `float`s, but `WithinULP(1., 1)` will expect to compare `double`s.
+
 
 ## Custom matchers
 It's easy to provide your own matchers to extend Catch or just to work with your own types.

 ## Adding your own command line options
 
-Catch embeds a powerful command line parser which you can also use to parse your own options out. This capability is still in active development but will be documented here when it is ready.
+Catch embeds a powerful command line parser called [Clara](https://github.com/philsquared/Clara). 
+As of Catch2 (and Clara 1.0) Clara allows you to write _composable_ option and argument parsers, 
+so extending Catch's own command line options is now easy.
+
+```c++
+#define CATCH_CONFIG_RUNNER
+#include "catch.hpp"
+
+int main( int argc, char* argv[] )
+{
+  Catch::Session session; // There must be exactly one instance
+  
+  int height = 0; // Some user variable you want to be able to set
+  
+  // Build a new parser on top of Catch's
+  using namespace Catch::clara;
+  auto cli 
+    = session.cli() // Get Catch's composite command line parser
+    | Opt( height, "height" ) // bind variable to a new option, with a hint string
+        ["-g"]["--height"]    // the option names it will respond to
+        ("how high?");        // description string for the help output
+        
+  // Now pass the new composite back to Catch so it uses that
+  session.cli( cli ); 
+  
+  // Let Catch (using Clara) parse the command line
+  int returnCode = session.applyCommandLine( argc, argv );
+  if( returnCode != 0 ) // Indicates a command line error
+  	return returnCode;

+## Version detection
+
+Catch provides a triplet of macros providing the header's version, 
+
+* `CATCH_VERSION_MAJOR`
+* `CATCH_VERSION_MINOR`
+* `CATCH_VERSION_PATCH`
+
+these macros expand into a single number, that corresponds to the appropriate
+part of the version. As an example, given single header version v2.3.4,
+the macros would expand into `2`, `3`, and `4` respectively.

-# 2.0.0 (in progress)
+
+# 2.2.0
+
+## Fixes

+* [Added a way to override the fallback stringifier](https://github.com/catchorg/Catch2/blob/master/docs/configuration.md#fallback-stringifier) (#1024)
+  * This allows project's own stringification machinery to be easily reused for Catch
+* `Catch::Session::run()` now accepts `char const * const *`, allowing it to accept array of string literals (#1031, #1178)
+  * The embedded version of Clara was bumped to v1.1.3
+* Various minor performance improvements
+* Added support for DJGPP DOS crosscompiler (#1206)

+  * Catch specific CMake options were prefixed with `CATCH_` for namespacing purposes
+  * Other changes to simplify Catch2's packaging

 * `*_THROWS_AS(expr, exception_type)` now unconditionally appends `const&` to the exception type.
 * `CATCH_CONFIG_FAST_COMPILE` now affects the `CHECK_` family of assertions as well as `REQUIRE_` family of assertions
   * This is most noticeable in `CHECK(throws())`, which would previously report failure, properly stringify the exception and continue. Now it will report failure and stop executing current section.
+* Removed deprecated matcher utility functions `Not`, `AllOf` and `AnyOf`.
+  * They are superseded by operators `!`, `&&` and `||`, which are natural and do not have limited arity
+* Removed support for non-const comparison operators
+  * Non-const comparison operators are an abomination that should not exist
+  * They were breaking support for comparing function to function pointer
+* `std::pair` and `std::tuple` are no longer stringified by default
+  * This is done to avoid dragging in `<tuple>` and `<utility>` headers in common path
+  * Their stringification can be enabled per-file via new configuration macros
+* `Approx` is subtly different and hopefully behaves more as users would expect

-## Getting Catch
+## Getting Catch2
 
-The simplest way to get Catch is to download the latest [single header version](https://raw.githubusercontent.com/philsquared/Catch/master/single_include/catch.hpp). The single header is generated by merging a set of individual headers but it is still just normal source code in a header file.

 ## Where to put it?
 
-Catch is header only. All you need to do is drop the file(s) somewhere reachable from your project - either in some central location you can set your header search path to find, or directly into your project tree itself! This is a particularly good option for other Open-Source projects that want to use Catch for their test suite. See [this blog entry for more on that](http://www.levelofindirection.com/journal/2011/5/27/unit-testing-in-c-and-objective-c-just-got-ridiculously-easi.html).

 While Catch fully supports this way of working there are a few problems with the approach. In particular the way your code must be split up, and the blunt granularity of it, may cause problems. You can only have one setup/ teardown pair across a set of methods, but sometimes you want slightly different setup in each method, or you may even want several levels of setup (a concept which we will clarify later on in this tutorial). It was <a href="http://jamesnewkirk.typepad.com/posts/2007/09/why-you-should-.html">problems like these</a> that led James Newkirk, who led the team that built NUnit, to start again from scratch and <a href="http://jamesnewkirk.typepad.com/posts/2007/09/announcing-xuni.html">build xUnit</a>).

 If you name your test cases and sections appropriately you can achieve a BDD-style specification structure. This became such a useful way of working that first class support has been added to Catch. Scenarios can be specified using ```SCENARIO```, ```GIVEN```, ```WHEN``` and ```THEN``` macros, which map on to ```TEST_CASE```s and ```SECTION```s, respectively.
