The kfile_chemical Documentation
If you want to start hacking on kfile_chemical, this page tells you how you can best start. This documentation is written by Egon Willighagen, egonw@users.sf.net
The kfile_chemical plugins are kfile plugins that make KDE aware of chemistry data formats. It's a set of simple plugin classes that are rather monolithic. Each plugin class resides in their own subdirectory, and the directory name indicates the MIME type associated with that plugin (or mostly at least). The MIME is "chemical/" plus the directory name.
You often find Jerome and me on irc on the freenode network, channel #cdk.
Have fun!
