       ifeffit - an interactive program for XAFS analysis


       ifeffit [options] files...


       This  manual  page  documents briefly the ifeffit command.  This manual
       page was written for  the  Debian  distribution  because  the  original
       program  does not have a manual page.  Instead, it has documentation in
       the GNU Info format; see below.

       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.

        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,  two  graphical  user   interfaces:   one   called
       G.I.FEFFIT,  and  one called ATHENA are built on the underlying IFEFFIT
       library. IFEFFIT and both GUIs are under active  development,  but  are
       fairly well tested and ready for use.


       These  programs  follow  the  usual  GNU command line syntax, with long
       options starting with two  dashes  (‘-’).   A  summary  of  options  is
       included below.  For a complete description, see the Info files.

       -h, --help
              Show summary of options.

       -x     Exit after running script files.

       -q     Run quietly, with no screen output.

       -n     Disable ’Ifeffit>’ prompt.

       -i     Show installation directory and exit.

       -v, --version
              Show version of program.
