Re: gEDA-user: Using mm units in .pcb files

[DJ Delorie <dj@xxxxxxxxxxx>]

The format we use for pcb-menu.res and gpcb-menu.res.  It's a
heirarchical text format with tagging and grouping.  Semantically,
it's like XML, but without all the heavy baggage that comes with XML.
It allows forward compatibility and third-party expansion, is easy to
parse, and highly compressible (since it's still text).  We'd probably
need to write Perl modules to read/write it though ;-)

Example:

(Element
  units = "mil"
  mark = (150 150)
  angle = 90
  refdes = ("U4" x=500 y=1800 scale=10)
  description = "monostable timer"
  value = "NE555D"
  origin_file = "semi/DIP-8-300.fp"
  lines = (
    size = 5
    (0 0 100 0)
    (0 0 0 100)
    (100 0 0 100 size=10)
  )
  pins = (
    drill = 35
    size = 75
    mask = 80
    clearance = 10
    (0 0)
    (100 0)
    (200 0)
    (300 0)
    (300 300)
    (200 300)
    (100 300)
    (0 300)
  )
)
