Description:
graphical diff program
Fldiff is a graphical diff program that shows the differences between two files/directories, or a file/directory and a CVS or Subversion repository. It is inspired by xdiff (Motif-based) and xxdiff (Qt-based), whose choice of GUI toolkit has hampered their portability to many of the systems. . Fldiff uses the Fast Light Toolkit (FLTK) and has been tested on AIX, IRIX, Linux, MacOS X, and Solaris, and should also run on Windows.
