kicad smd_transistors library has incorrect sot23 pin numbers
The standard kicad library (at least in 2013-mar-13 -testing) smd_transistors.mod has an sot23 footprint with pin numbering that is not the commonly used sot23 layout.
The most common layout is:
With the pins numbered anti clockwise as is normally the case with most ICs. This makes pin 3 the pin on the single-pin side of an sot23.
The package in smd_transistors has them numbered this way:
With the single pin side being given pin 2. Very few sot23 devices use this layout.
This caught me out on a PCB I had manufactured. I should still have checked every pin-out provided, but I missed this one :(
