Libxaw7 provides the second version of xaw, the athena widgets toolkit, which is largely used by legacy x applications. this version is the most common version, as version 6 is considered deprecated, and version 8, which adds xprint support, is unsupported and not widely used. in general, use of a more modern toolkit such as gtk+ is recommended.
