 PacketCommand
 =============
 A simple light-weight Wiring/Arduino library to dispatch binary packet commands 
-to user configurable handler functions.  The term "packet" here is used to refer
-to a variable length grouping of bytes that has a well-defined structure.  A 
+to user configurable handler functions.  The style of the API was inspired heavily 
+by a fork of [Arduino-SerialCommand](https://github.com/p-v-o-s/Arduino-SerialCommand); 
+the orginal version of that library was written by [Steven Cogswell](http://husks.wordpress.com) (published May 23, 2011 in his blog post ["A Minimal Arduino Library for Processing Serial Commands"](http://husks.wordpress.com/2011/05/23/a-minimal-arduino-library-for-processing-serial-commands/)).

+The term "packet" here is used to refer to a variable length grouping of bytes that has a well-defined structure.  A 
 valid packet must start with a variable length byte sequence that is 
 interpreted as its "type ID".  A valid type ID is defined like this:
 [```0x01-0xFE```] or [```0xFF01-0xFFFE```] or ```...```; that is, if it starts
