+# Generic Travis CI build script for boostorg repositories
+# See: https://github.com/boostorg/boost-ci
+#
+# Instructions for customizing this script for your library:
+#
+# 1. Customize the compilers and language levels you want in the 'jobs'.
+# 2. If you have more than include/, src/, test/, example/, examples/, or
+#    tools/ directories, modify your Travis CI project and add the environment
+#    variable DEPINST.  For example if your build uses code in "bench/" and
+#    "fog/" directories, then set DEPINST to the following:
+#        --include bench --include fog
+# 3. If you want to enable Coverity Scan, you need to provide the environment
+#    variables COVERITY_SCAN_TOKEN and COVERITY_SCAN_NOTIFICATION_EMAIL in
+#    your github settings.
+# 4. Enable pull request builds in your boostorg/<library> account.
+#
+# That's it - the scripts will do everything else for you.

+* [Report bugs](https://github.com/boostorg/algorithm/issues): Be sure to mention Boost version, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
+* Submit your patches as pull requests against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](http://www.boost.org/LICENSE_1_0.txt).
+* Discussions about the library are held on the [Boost developers mailing list](http://www.boost.org/community/groups.html#main). Be sure to read the [discussion policy](http://www.boost.org/community/policy.html) before posting and add the `[algorithm]` tag at the beginning of the subject line.

+
+The header file [^[link header.boost.algorithm.apply_permutation_hpp apply_permutation.hpp]] contains two algorithms, `apply_permutation` and `apply_reverse_permutation`. There are also range-based versions.
+The algorithms transform the item sequence according to index sequence order.
+
+The routine `apply_permutation` takes a item sequence and a order sequence. It reshuffles item sequence according to order sequence. Every value in order sequence means where the item comes from. Order sequence needs to be exactly a permutation of the sequence [0, 1, ... , N], where N is the biggest index in the item sequence (zero-indexed).
+The routine `apply_reverse_permutation` takes a item sequence and a order sequence. It will reshuffle item sequence according to order sequence. Every value in order sequence means where the item goes to. Order sequence needs to be exactly a permutation of the sequence [0, 1, ... , N], where N is the biggest index in the item sequence (zero-indexed).
+
+Implementations are based on these articles:
+https://devblogs.microsoft.com/oldnewthing/20170102-00/?p=95095

+https://devblogs.microsoft.com/oldnewthing/20170111-00/?p=95165
+
+The routines come in 2 forms; the first one takes two iterators to define the item range and one iterator to define the beginning of index range. The second form takes range to define the item sequence and range to define index sequence.
+
+
+[heading interface]
+
+There are two versions of algorithms:
+1) takes four iterators.
+2) takes two ranges.

+`apply_permutation` and 'apply_reverse_permutation' work only on RandomAccess iterators. RandomAccess iterators required both for item and index sequences.

+
+[heading Exception Safety]
+
+All of the variants of `apply_permutation` and `apply_reverse_permutation` take their parameters by iterators or reference, and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee.
+
+[heading Notes]
+* If ItemSequence and IndexSequence are not equal, behavior is undefined.
+
+* `apply_permutation` and `apply_reverse_permutation` work also on empty sequences.
+
+* Order sequence must be zero-indexed.
+
+* Order sequence gets permuted.

+
+The header file 'find_backward.hpp' contains variants of the stl algorithm
+`find`. These variants are like `find`, except that the evaluate the elements
+of the given sequence in reverse order.
+
+Consider how finding the last element that is equal to `x` in a range is
+typically done:
+
+    // Assume a valid range if elements delimited by [first, last).
+    while (last-- != first) {
+        if (*last == x) {
+            // Use last here...
+        }
+    }
+
+Raw loops are icky though.  Perhaps we should do a bit of extra work to allow
+the use of `std::find()`:
+
+    auto rfirst = std::make_reverse_iterator(last);
+    auto rlast = std::make_reverse_iterator(first);
+    auto it = std::find(rfirst, rlast, x);
+    // Use it here...
+
+That seems nicer in that there is no raw loop, but it has two major drawbacks.
+First, it requires an unpleasant amount of typing.  Second, it is less
+efficient than forward-iterator `find` , since `std::reverse_iterator` calls
+its base-iterator's `operator--()` in most of its member functions before
+doing the work that the member function requires.

+
+The header file 'find_not.hpp' contains a variants of a the stl algorithm
+`find`. The algorithm finds the first value in the given sequence that is not
+equal to the given value.
+
+Consider this use of `find()`:
+
+    std::vector<int> vec = { 1, 1, 2 };
+    auto it = std::find(vec.begin(), vec.end(), 1);
+
+This gives us the first occurance of `1` in `vec`.  What if we want to find
+the first occurrance of any number besides `1` in `vec`?  We have to write an
+unfortunate amount of code:
+
+    std::vector<int> vec = { 1, 1, 2 };
+    auto it = std::find_if(vec.begin(), vec.end(), [](int i) { return i != 1; });
+
+With `find_not()` the code gets much more terse:
+
+    std::vector<int> vec = { 1, 1, 2 };
+    auto it = find_not(vec.begin(), vec.end(), 1);
+
+The existing `find` variants are: `find()`, `find_if()`, and `find_if_not()`.
+It seems natural to also have `find_not()`, for the very reason that we have
+`find_if_not()` -- to avoid having to write a lambda to wrap the negation of
+the find condition.
+

+
+These overloads of `find_not` return the first value that is not equal to `x`
+in the sequence `[first, last)` or `r`, respectively.
+
+[heading Examples]
+
+Given the container `c1` containing `{ 0, 1, 2 }`,  then

+
+[heading Iterator Requirements]
+
+`find_not` works on all iterators except output iterators.
+
+The template parameter `Sentinel` is allowed to be different from `InputIter`,
+or they may be the same.  For an `InputIter` `it` and a `Sentinel` `end`, `it
