+# libasio
+
+Asio is a cross-platform C++ library for network and low-level I/O programming
+that provides developers with a consistent asynchronous model using a modern
+C++ approach.
+
+Asio provides the basic building blocks for C++ networking, concurrency and
+other kinds of I/O. Asio is used in all kinds of applications, from phone apps
+to the world’s fastest share markets.
+
+For more information see: https://think-async.com/Asio/
+
+This is a `build2` package for the standalone version of the Asio library.
+
+# Usage
+
+This package provides the `lib{asio}` library.
+
+SSL support is disabled by default. To enable it, add the following to your
+`manifest`:
+
+```
+depends:
+\
+libasio ^1.28.0
+{
+  require
+  {
+    config.libasio.ssl = true
+  }
+}
+\
+```
+
+Note that on some platforms (such as MinGW) it may be necessary for
+applications to define `_WIN32_WINNT` to an appropriate value. If it's not
+defined the library's `config.hpp` header will issue a warning and choose a
+default (currently `0x0601`, meaning Windows 7 and later; this is also the
+value that the library is built with).
