+function2 improved and configurable drop-in replacement header to 
+std::function that supports move only types, multiple overloads
+and more
+
+benefits and improvements over std::function:
+
+ * const, volatile, reference and noexcept correct (qualifiers are part
+   of the operator() signature)
+ * convertible to and from std::function as well as other callable
+   types
+ * adaptable through fu2::function_base (internal capacity,
+   copyable and exception guarantees)
+ * overloadable with an arbitrary count of signatures
+   (fu2::function<bool(int), bool(float)>)
+ * full allocator support in contrast to std::function, which doesn't
+   provide support anymore
+ * covered by many unit tests and continuous integration services
+   (GCC, Clang and MSVC)
+ * header only, just copy and include function.hpp in your project
+ * permissively licensed under the boost license

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
