This piece of software is an unofficial fork of BKChem, which is a free molecular drawing program.

For the official version, more info on program capabilities, install instructions etc. see documentation in directory "doc" in the main BKChem directory or the BKChem website on http://zirael.org/bkchem/

Bug reports and suggestions please contact: Simone Pilon wertyseek@gmail.com

BKChem is free software and is distributed under GNU GPL. The program is provided as is without warranty of any kind. For details see the file "gpl.txt" in main bkchem directory.

For installation instructions see the file INSTALL in main BKChem directory.

NOTE: Starting with the version 0.9.0-pre1 Piddle sources are shipped together with BKChem. Piddle is a library provided under the GPL license and seems to be dead at least 2 years. Therefore it was decided to put it inside BKChem sources and distribute any eventual additions this way. In case any major changes will be made Piddle will be released as a standalone library.

NOTE: Starting with the version 0.10.0-pre1 Pmw (http://pmw.sourceforge.net/) sources (version 1.2) are shipped together with BKChem. There were needed some minor fixes in Pwm and as it is a library provided under the GPL license and seems to be dead it was decided to put it inside bkchem sources and distribute the fixed version this way.

NOTE: The official InChI software from IUPAC is bundled in a binary form together with BKChem in Windows binary builds. All the credit for this nice piece of software goes to its creators. This information comes with the software:
