BABEL is a program designed to interconvert a number of file formats
currently used in molecular modeling.  The program is available for
Unix (AIX, Ultrix, Sun-OS, Convex, SGI, Cray, Linux), MS-DOS, and  
Macs running at least System 7.0.

Babel will currently read the following file formats :

Mopac Cartesian 	Mopac Internal		Mopac Output
CSD GSTAT		CSD CSSR		Free Form Fractional 
Macromodel 		MM2 Ouput 		PDB 
Alchemy			XYZ 			Mac Molecule
Chem3D			MicroWorld		Ball and Stick
MOLIN

Babel will currently write the following formats :

Mopac Cartesian		Mopac Internal 		Gaussian Input 
IDATM			Macromodel 		Mac Molecule
MM2 Input 		MM2 Ouput		PDB file
Report of interatiomic distances, angles, and torsions
Alchemy			XYZ 			Ball and Stick
Chem3D			MicroWorld		

Babel is capable of assigning hybridization, bond order, connectivity
when these elements are not present in the input file.  Babel is also 
capable of adding and deleting hydrogens from a structure.

HOW TO OBTAIN BABEL

Babel is available by anonymous ftp from joplin.biosci.arizona.edu in the
directory pub/Babel.  Login as anonymous and give your e-mail address as 
a password.

INSTALLATION OVERVIEW

UNIX

The Unix version is in the file babel.tar.Z

1. uncompress babel.tar.Z
2. tar -xvf babel.tar 
3. follow the instructions in README.1ST

------------- Special note to those with Sun workstations ---------------
Unfortunately many Sun workstations have non-ANSI C compliers. Those with
Sun workstations have two choices:
- compile Babel with gcc
- download the file babel-sun.tar.Z which contains an executable binary
compiled with gcc under SunOS 4.1.1
--------------------------------------------------------------------------

MAC
The Mac version is in the file macbabel.sea.hqx

1. UnBixhex the file with StuffIt Expander, CompactPro or whatever.
2. Double click on the self extracting archive macbabel.sea
3. Follow the instructions in the file Babel Manual.

DOS
The DOS version is in the file dosbabel.zip

1. pkunzip dosbabel.zip
