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

Babel will read the following file types :

Alchemy                  AMBER PREP               Ball and Stick           
Biosym .CAR              Boogie                   Cacao Cartesian

XYZ                      

Babel is capable of assigning hybridization, bond order, and connectivity 
when these elements are not present in the input file.

NOTE:  The file formats indicated with * are not currently supported in the
Mac version.  We're currently working on a Mac update which will include all
these formats, and few other new goodies.  This update should be ready in a
couple of weeks.

INSTALLATION OVERVIEW
Babel is avialiable via annonymous ftp from 
joplin.biosci.arizona.edu in pub/Babel

UNIX

The Unix version is in the file babel-1.04.tar.Z

1. uncompress babel-1.04.tar.Z
2. tar -xvf babel-1.04.tar 
3. follow the instructions in README.1ST

-------Special note for users with Sun workstations-------------------
Many older Sun C compilers are not ANSI compliant and will not compile 
Babel.  However, there are two options :
1. Use gcc
2. Download the file sun-babel.tar.Z which has a binary compiled with
with gcc on a sun 4 under SunOS release 4.1.3. 

-------Specail note for users with SGI workstations-----------------------
It seems that some people who have SGI workstations don't have a C compiler.
For these people we have put an SGI binary in the file sgi-babel.tar.Z

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

1. Use you favorite archiving program to unbinhex the archive.
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 babel104.zip

1. pkunzip babel104.zip
2. follow the instructions in README.1ST
