+SUMMARY="Library for building powerful interactive command line applications in Python"
+DESCRIPTION="prompt_toolkit could be a replacement for GNU readline, but it can be much \
+more than that.
+
+Some features:
+
+- Pure Python.
+- Syntax highlighting of the input while typing. (For instance, with a Pygments lexer.)
+- Multi-line input editing.
+- Advanced code completion.
+- Both Emacs and Vi key bindings. (Similar to readline.)
+- Even some advanced Vi functionality, like named registers and digraphs.
+- Reverse and forward incremental search.
+- Works well with Unicode double width characters. (Chinese input.)
+- Selecting text for copy/paste. (Both Emacs and Vi style.)
+- Support for bracketed paste.
+- Mouse support for cursor positioning and scrolling.
+- Auto suggestions. (Like fish shell.)
+- Multiple input buffers.
+- No global state.
+- Lightweight, the only dependencies are Pygments and wcwidth.
+- Runs on Linux, OS X, FreeBSD, OpenBSD and Windows systems.
+- And much more..."
