Chemistry/File::SMILES version 0.32
===================================

This object-oriented module parses and produces SMILES (Simplified Molecular
Input Line Entry Specification) strings. It is a File I/O driver for the PerMol
Toolkit.

For more information about SMILES, see The SMILES Home Page at
http://www.daylight.com/dayhtml/smiles/

This module is under development and doesn't implement the full SMILES syntax
yet.

Missing features:
* Branches that start before an atom, such as (OC)C, which should be
 equivalent to C(CO) and COC, according to some variants of the SMILES
 specification. Many other tools don't implement this rule either.
* Proper handling of aromatic atoms.
* Unique (canonical) SMILES output.

CHANGES SINCE VERSION 0.31
       - Changed the way disconnected structures are handled. Now "bonds" of
         type . (dot) don't produce any bond in the molecule object (previous
         versions added a bond with order=0).

INSTALLATION

To install this module type the following:

  perl Makefile.PL
  make
  make test
  make install

DEPENDENCIES
