       Interactive fit environment suplying a frontend for
       reading/fitting/plotting/analysing data

       cafe

       cafe, logfile=logfile

      No explicite. Must be get interactively from internal command
      line.

       logfile - file name where to write commands/result
                            of cafe into. No log will be performed
                            if this command is not given.

       noinit  - Do not execute .caferc files both in $HOME/.caferc
                 and $PWD/.caferc
       nolog   - Do not automatically create a log file.

       No explicite. Will be written to file from internal command
       line.

       None.

       None except the one used by mpfit.

       None. If not crashing.

       CAFE can be initialized with scripts which are executed
       automatically when starting up. These are (executed in this
       order):
       1.) $HOME/.caferc - The global user personal init file. If $HOME
                           is not defined the file could not be
                           executed. This  means also that this
                           mechanism can be used for unix-like systems
                           only.
       2.) $PWD/.caferc  - A lokal initial file. The file must reside
                           within the current working directory.

       CAFE is intended for interactive use; therefore
       this program should not be called within  a batch file (if
       not this script performs interactive processes itself).

       CAFE shows a prompt and allows to enter several
       commands to perform a fitting cycle. Each command
       follows a nearly IDL-like syntax:
             command> {parameters,}{<opt_parameter>=,}{/,,}
       Most important commands:
           -  help [<command>] : prints list of available
                                commands, or of a single command
                                given.
           - quit : exit the environment. Do not interrupt for
                    the environment uses pointer objects which must be
                    freed after processing.

       This environment was built at the Institute for
       Astronomy and Astrophysic Tuebingen (IAAT),
       http://astro.uni-tuebingen.de).
       Design, structure and basic commands are
       created by Eckart Goehler, 2002.
