Interactive XAFS analysis program

IFEFFIT is an interactive program for XAFS analysis. It combines the high-quality analysis algorithms of AUTOBK and FEFFIT with graphical display of XAFS data and general data manipulation. IFEFFIT comes as a command-line program, but the underlying functionality is available as a programming library. The IFEFFIT library can be used from C, Fortran, Tcl, Perl, and Python. This allows a variety of user interfaces (both graphical and non-graphical) to be written around IFEFFIT. Currently, three graphical user interfaces: G.I.FEFFIT, ATHENA/ARTEMIS, and SIXPACK are built on the underlying IFEFFIT library. IFEFFIT and all three GUIs are under active development, but are fairly well tested and ready for use.
