Basically, what you are not allowed to do is take any code that came with Chimera with copyright notice attached and use it directly as the basis for your plugin. What you are allowed to do is to look at the Chimera code and see how it performs various functions and write analogous code yourself, or call into the various methods provided by Chimera to do things you need done. Any code we provide without copyright (e.g. the programming examples) you can use directly.</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>The purpose of the legalese is to prevent someone from taking Chimera or a substantial subpart and distributing it as their own program. It is not to stifle people trying to develop plugins like yourself.</div><div class=""><br class=""></div><div class="">—Eric<br class=""><div class="">
