Below is the original README file from the IRIX distribution.
We suggest you use the Perl script "multidock.perl" in place of the shell
script "multidock", as it does not require you to set system enviroment
variables.
Also included is an example Perl script to run multidock on a ftdock type
data file.
IMPORTANT - because of the way the multidock program outputs PDB, the
program "profit" is required by these perl scripts to reconstruct proper
PDB style files.

===========================================================================

MULTIDOCK v1.0

This version runs on Silicon Graphics machines
running Irix 5.3 and above. 
 
The tar file contains the following:

executables
-----------
multidock (shell script that runs overall program)
hydtor
mcopy  
multidock_main
rearrange
rotenergy
torpdb

Data files
----------
AATOR.DAT
HYDROGENS.DAT
ROT.LIB
ROT.OCC
params.dat_example (example of a control_parameters file)

The program is run from a shell script, multidock, in
which the environment variable $MULTIDIR is defined.
Hence MULTIDIR must be defined in your .cshrc 

e.g.
    setenv MULTIDIR /usr/people/bloggs/multidock

You then might consider running MULTIDOCK for a protein
complex in the Protein Data Bank. The file
"params.dat_example" included here is compatible with 
pdb2ptc.ent (Trypsin/BPTI complex) 

e.g.
    % multidock /pdb/pdb2ptc.ent 2ptc.pdbmodel params.dat_example
