  13 - Changes to add the gerber driver:
  14         + dev_gerber.h          Clone from dev_ps.h.
  15         + dev_gerber.c          Clone from dev_ps.c.
  16                                 Added support for the Outline & Alignment
  17                                         device operation.
  18         + dev_gerberX.h         Clone from dev_gerber.h
  19         + dev_gerberX.c         Clone from dev_gerber.c
  20                                 Added support for the Outline & Alignment
  21                                         device operation.
  22         + default_aperture      Changes for new pads and changed formats
  23                                         with leading D & X for the two
  24                                         different gerber standards.
  25         + data.h                Up size of PrintingDevice.
  26         + data.c                Include "dev_gerber.h" & "dev_gerberX.h"
  27         + print.h               Added support for the "Render Text on
  28                                         Silkscreen" option.
  29         + print.c               Include "dev_gerber.h" & "dev_gerberX.h" *A*
  30                                 Disable silkscreening of pads and pins; these
  31                                         surfaces must be soldered and
  32                                         should not be silkscreened.
  33                                 Added support for the Text() device operation.
  34                                 Added support for the "Render Text on
  35                                         Silkscreen" option.
  36         + printdialog.c         Include "dev_gerber.h" & "dev_gerberX.h" *A*
  37                                 Added support for the "Render Text on
  38                                         Silkscreen" option.
  39         + const.h               Up limit on maximum number of print/output
  40                                 files.
  41         + Imakefile             Include support for dev_gerber.[co].
  42                                         & dev_gerberX.[co]
  43         + pcbtogbr.gcf          Created default gerber control file (gcf).
  44                                 This belongs in the layout file, also.
  45         + pcbtogbr.pcb          Created test data file.
  46         + *.gbr                 Generated Gerber files from pcbtogbr.pcb
  47         + *.gbx                 "ditto" ^^^^ for Gerber Extented
  48         + gerbertotk.c          Converts Gerber files to tcl/tk programs.
  49         + gbrtest               Exports test gerber conversion data to a
  50                                         MS-DOG subdirectory for testing
  51                                         via a Gerber interpreter.
  52         + ../config.h           Amended the RELEASE definition to protect the
  53                                         innocent.
  54         + global.h              Added support for the Text() device operation.
  55         + dev_ps.c              Added support for the Text() device operation.
  56         + ../lib/*.*            Added Radial & Axial Caps, Axial Resistors,
  57                                         14-pin can oscillators, one generic
  58                                         matched pair of transistors
  59                                         2N3904 NPN & 2N3906 PNP,
  60                                         ovenized oscillator, etc...
  61
  62         ALPHA.06
  63
  64         + dev_gerberX.c         Deleted RS-274X calls to read default_aperture
  65                                         file.  gerberX now generates internal
  66                                         aperture information specific to each
  67                                         layer.  ApertureFunctions deleted,
  68                                         since the G0(1|2|3) deterrmine the
  69                                         action to be taken.
  70
  71                                 Tested with OrCAD GerberTool Demo 6.2b1,
  72                                         it works but some the silkscreens for
  73                                         arcs are wacky.  Most items have a
  74                                         normal appearance with GO3 CCW draw
  75                                         command.
  76         + Device->(function)    Any file that has this type of call got
  77                                         assaulted and had an "int unused"
  78                                         added.
  79
  80         + dev_gerber.c          Working on having a file called
  81                                         "default.map" or "default.app"
  82                                         to dynamically generate an aperture
  83                                         table that is dependent on the
  84                                         gerber RS-274D file generation.
  85 --- PCB 1.4.5.ALPHA.02a
  86
  87         + dev_gerber.c          gerber RS-274D now does dynamic aperture
  88                                         table generation
  89 - Note: *A*
  90         + It might not be needed to include dev_*.h within this source
  91                 files.  Investigate.
