After a while, you also realize that library design is more complicated
than you thought, if you're sending the board out and want to have
the silkscreen and soldermask and all those "other" layers "just right."

I have just received a board with a DGS-0179 connector to a wall wart.  I
also got a Mouser package with the connector itself.  I made the part in
Eagle from the data sheet, and it worked as expected.  The two alignment
holes are a bit loose, but that is because I moved both drills up to the
begger standard Olimex drill size. (Plated through, not connected, no extra
charge.)

So, I have now edited the library part, and I have placed a large rectangle
in the "tDocu" layer and enclosed text that says "Clearance for Plug" just
so the next board has the opening facing off-board. (ROTFL) I just have to
remember to display tDocu from time to time.

On my board, I have moved the defaults between the "name" and "value"
layers so that the silkscreen says, e.g., "470 p" instead of "C3"  On the
last prototype run, I was able to open the Mouser package and the Olimex
package and sit and solder a working board, using only the silkscreen as
documentation.

However, I have learned to notice when I am putting a lot of time changing
how the defaults are.  I suppose that the trade off is that it is much
easier for a hobbyist to assemble my board with the values on the board,
but reading the schematic is difficult.

Do other people put the values on the silkscreen instead of the schematic
designation?
