<description>&lt;h3&gt;SparkFun Electronics' preferred foot prints&lt;/h3&gt;
In this library you'll find discrete semiconductors- transistors, diodes, TRIACs, optoisolators, etc.&lt;br&gt;&lt;br&gt;
We've spent an enormous amount of time creating and checking these footprints and parts, but it is the end user's responsibility to ensure correctness and suitablity for a given componet or application. If you enjoy using this library, please buy one of our products at www.sparkfun.com.
&lt;br&gt;&lt;br&gt;
&lt;b&gt;Licensing:&lt;/b&gt; CC v3.0 Share-Alike You are welcome to use this library for commercial purposes. For attribution, we ask that when you begin to sell your device using our footprint, you email us with a link to the product being sold. We want bragging rights that we helped (in a very small part) to create your 8th world wonder. We would like the opportunity to feature your device on our homepage.</description>
