Xfig is an interactive drawing tool which runs under X Window System Version 11 Release 4 ( X11R4 ) or later, on most UNIX-compatible platforms, and e.g. under Darwin on the MacIntosh and any X server under Microsoft Windows. Xfig is freeware. Xfig saves figures in its native Fig format, but they may be converted into various formats such as PostScript, GIF, JPEG, HP-GL, etc.
