There a "fixme" under "Footprint basics" and there is a description
of that in the pcb.pdf manual "9.2.1 Creating Newlib Footprints":
===
To create
1. Start PCB with an empty layout.
2. Make the component layer active.
3. For a leaded part, select the via tool and place vias where the pads for the part should
go. For surface mount pads, draw line segments. Note that until the footprint is
completed, the surface mount pads will remain rounded. Currently a rectangle or
polygon may not be used as a pad.
4. For each via and line segment which will become a pad, select it and press 'n' to be
able to enter a name. Enter the pin number and press enter.
5. Make the silk layer active.
6. Using the line and arc tools, draw a silk screen outline for the part.
7. Using the selection tool, select all of the pins and silk screen for the part.
8. Place the pointer above the reference point for the part. This is typically the common
centroid. Keeping the pointer there, shift-right-click to bring up the popup menu and
choose "convert selection to element".
9. At this point, the vias, line segments, and silk screen will have been converted to an
element. To change any of the line segments to have square ends rather than round
ends, select the pads by holding down the shift key and clicking each pad with the
center mouse button. Now under the Select menu, "Change square-flag of selected
objects" section, choose "Pins".
10. Select the element, shift-right-click to bring up the popup menu, and choose "Copy
Selection to Buffer". Now left-click on the center of the new element.
11. Under the buffer menu, choose "save buffer elements to file" to save the new footprint
to a file.
12. Press ESC to exit from buffer mode.

I tried it, and except for the shift-rigth-click thing, it worked.
Should one copy the text or give a reference the pdf ?

Ahh, without your help it wouldn't be any difference.
