<description>&lt;b&gt;Male(J), Female(P) and Pin Headers&lt;/b&gt;&lt;p&gt;Version 1.02 - 03/10/2009&lt;p&gt;
This library is a collection of various pin headers and AMP, Molex and 3M board-to-board connectors. 
This library assumes the notion of JACKS(male) and PLUGS(female) as represented by the J and P symbols.
Standard male/female pin header types are available in common 0.1" and 2 mm pitch types with alternate mirrored footprints as well.
