To install ProFit, unpack the tar file. This will create a ProFit
directory containing the profit executable and other support
files.

Move the executable called profit to somewhere in your path.

Under UNIX-like operating systems, you should now create the
environment variables HELPDIR and DATADIR. These should both point
to the top ProFit directory where the files ProFit.help and
mdm78.mat are stored.
e.g.
(csh)   setenv HELPDIR /home/andrew/ProFitV2.2
        setenv DATADIR /home/andrew/ProFitV2.2
(sh)    export HELPDIR=/home/andrew/ProFitV2.2
        export DATADIR=/home/andrew/ProFitV2.2

Alternatively, you may wish to store these files elsewhere, or have
all help files and data files in a single directory.

Under VAX/VMS-like operating systems, these should be ASSIGNs.
e.g.
ASSIGN $A:[ANDREW.PROFIT] DATADIR
ASSIGN $A:[ANDREW.PROFIT] HELPDIR



You are now ready to run ProFit. You may specify the PDB files on the
command line and may use a -h flag to include HETATM records.  If you
do not specify the files, you may read them in with the REFERENCE and
MOBILE commands. The HETATOM and NOHETATOM commands toggle the reading
of HETATM records.

Once in ProFit, type HELP for further information.
