<description>&lt;h3&gt;SparkFun Electronics' preferred foot prints&lt;/h3&gt;
In this library you'll find resistors, capacitors, inductors, test points, jumper pads, 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.

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>

<description>&lt;h3&gt;SparkFun Jumpers&lt;/h3&gt;
In this library you'll find jumpers, or other semipermanent means of changing current paths. The least permanent form is the solder jumper. These can be changed by adding, removing, or moving solder. In cases that are less likely to be changed we have jumpers that are connected with traces. These can be cut with a razor, or reconnected with solder. Reference designator JP.
