+[Boost.Function](http://boost.org/libs/function), part of the
+[Boost C++ Libraries](http://boost.org), is the original implementation of the
+polymorphic function wrapper `boost::function`, which was eventually accepted
+into the C++11 standard as [`std::function`](https://en.cppreference.com/w/cpp/utility/functional/function).

-* [Ask questions](http://stackoverflow.com/questions/ask?tags=c%2B%2B,boost,boost-function)
-* [Report bugs](https://github.com/boostorg/function/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 `[function]` tag at the beginning of the subject line.

-# Generic Appveyor build script for boostorg repositories
-# See: https://github.com/jeking3/boost-ci/
-#
-# Instructions for customizing this script for your library:
-#
-# 1. Customize the compilers and language levels you want.
-# 2. If you have move 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.
