--------------------------------------------------------------------------

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.  For versions of BABEL not supported
by CCP14, users are invited to browse the BABEL WWW home page :

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



                     ACQUISITION OF BABEL THROUGH CCP14
                     ---------------------------------- 


SGIRIX5.2  
---------  

     Users will find the compressed file "sgi-babel-1.1.tar.Z" in the CCP14
directory "/ccp14/sgirix5.2/babel".  First of all, "get" this file via
FTP, and then take the following steps :

(1) Type "uncompress sgi-babel-1.1.tar.Z".
(2) Type "tar -xvf sgi-babel-1.1.tar".

     The action of commands (1) and (2) above is to uncompress the original
tar file and put the contents in a directory "babel-1.1" immediately below
the current working directory.      

(3) Type "cd babel-1.1" to go down to directory "/babel-1.1", where you will
    find the BABEL executable and all files needed to run BABEL on SGIRIX.
    The file "README.1ST" contains full documentation and, having acquired
    the program as above, you shouldn't need to consult the section on
    installation.


SUNOS4.1.3
----------

     Users will find the compressed file "sun-babel-1.06.tar.Z" in the CCP14
directory "/ccp14/sunos4.1.3/babel".  First of all, "get" this file via
FTP, and then take the following steps :

(1) Type "uncompress sun-babel-1.06.tar.Z".
(2) Type "tar -xvf sun-babel-1.06.tar".

     The action of commands (1) and (2) above is to uncompress the original
tar file and put the contents in a directory "babel-1.06" immediately below
the current working directory.

(3) Type "cd babel-1.06" to go down to directory "/babel-1.06", where you will
    find the BABEL executable and all files needed to run BABEL on SUNOS.
    The file "README.1ST" contains full documentation and, having acquired
    the program as above, you shouldn't need to consult the section on
    installation.


ULTRIX4.2
---------

     The executable and ancillary files have already been uncompressed and
can be found in CCP14 directory "/ccp14/ultrix4.2/babel".  Please see the
file "README.1ST" for full documentation.


MS-DOS5.0
---------

     Users will find the file "babel16.zip" in the CCP14 directory
"/ccp14/pc-dos-windows/babel-dos-win/".  
Create a directory "\BABEL" on your own PC
and "get" babel16.zip using FTP.  Next, from directory "\BABEL" on your
PC, type "pkunzip babel16.zip".  The executable "babel.exe", together with
all ancillary files, will be downloaded into the current directory.   
For full documentation, see the file "README.1ST".
