 Newt is a windowing toolkit for text mode built from the slang library.

 push buttons, check boxes, radio buttons, lists, entry fields, labels,
 and displayable text. Scrollbars are supported, and forms may be nested
 to provide extra functionality. This package contains the shared library
 for programs that have been built with newt.
