Prima is an extensible Perl toolkit for multi-platform GUI development. Platforms supported include Linux, Windows NT/9x/2K, OS/2 and UNIX/X11 workstations (FreeBSD, IRIX, SunOS, Solaris and others). The toolkit contains a rich set of standard widgets and has emphasis on 2D image processing tasks. A Perl program using PRIMA looks and behaves identically on X, Win32 and OS/2 PM. The toolkit includes a visual builder. WWW: http://prima.eu.org/ - Dmitry Karasik, dmitry@karasik.eu.org
