+# 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.

+* [Ask questions](http://stackoverflow.com/questions/ask?tags=c%2B%2B,boost,boost-algorithm)
+* [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.

+# Instructions for customizing this script for your library:
+#
+# 1. Customize the compilers and language levels you want.
+# 2. If you have more than include/, src/, test/, example/, examples/,
+#    benchmark/ or tools/ directories, set the environment variable DEPINST.
+#    For example if your build uses code in "bench/" and "fog/" directories:
+#      - DEPINST: --include bench --include fog
+# 3. Enable pull request builds in your boostorg/<library> account.
+#
+# That's it - the script will do everything else for you.

-The header file 'apply_permutation.hpp' contains two algorithms, apply_permutation and apply_reverse_permutation. Also there are range-based versions. 
+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:

 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.

 Consider this use of `find()`:
 
-    auto std::vector<int> vec = { 1, 1, 2 };
+    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:
 
-    auto std::vector<int> vec = { 1, 1, 2 };
+    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:
 
-    auto std::vector<int> vec = { 1, 1, 2 };
+    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()`.
