Tgif is an interactive drawing tool that allows the user to draw and manipulate objects in the X Window System. It's also a hyper-graphics (or hyper-structured-graphics) browser on the World-Wide-Web. Its hyper-text home page is http://bourbon.usc.edu:8001/tgif/ and its hyper-graphics home page is http://bourbon.usc.edu:8001/tgif/index.obj. Tgif drawings can be converted to a variety of formats, including GIF, encapsulated PostScript and XBM. Version 4 has a completely revamped 3-D user interface, as well as a host of new features. Tgif depends on the `netpbm' package, available from the `ports' collection. Tgif is written, maintained and enhanced by William Chia-Wei Cheng (bill.cheng@acm.org) WWW: http://bourbon.usc.edu:8001/tgif/
