delete the old cad/pcb package. The package which has lived in cad/pcb
for the last few years was horribly out of date and pcb is not making
a distinction right now between -current snapshots and normal releases.

Release Notes for PCB snapshot 20050609
========================================================================
- **** The GUI is now based on gtk2 instead of Xaw **** This represents
a fairly major change. You will now need gtk-2.4 or higher installed
along with any of its dependencies to build pcb. On linux
distributions, it is probably the case that you already have this.
For *BSD, Solaris, and others, you may want to use NetBSD's pkgsrc
to help install gtk2 and its dependencies.
- Flags are stored symbolically in the .pcb file. This is the start
of moving to support >8 layers. Please note that >8 layer support
is not yet available in this snapshot.
- Fixes for gcc-4
- As part of the switch to gtk2, the user customizable menu feature has
been temporarily broken. Hopefully this will be fixed by the next
snapshot. In addition, the loading of background images has also been
temporarily broken.

run-time dependency (DEPENDS) on a tool is to append a ":run" modifier
to the tool name, e.g.,
USE_TOOLS+= perl:run
Tools without modifiers or with an explicit ":build" modifier will
cause build dependencies (BUILD_DEPENDS) on those tools to be added.
This makes the notation a bit more compact.

Several changes are involved since they are all interrelated. These
changes affect about 1000 files.
The first major change is rewriting bsd.builtin.mk as well as all of
the builtin.mk files to follow the new example in bsd.builtin.mk.
The loop to include all of the builtin.mk files needed by the package
is moved from bsd.builtin.mk and into bsd.buildlink3.mk. bsd.builtin.mk
is now included by each of the individual builtin.mk files and provides
some common logic for all of the builtin.mk files. Currently, this
includes the computation for whether the native or pkgsrc version of
the package is preferred. This causes USE_BUILTIN.* to be correctly
set when one builtin.mk file includes another.
The second major change is teach the builtin.mk files to consider
files under ${LOCALBASE} to be from pkgsrc-controlled packages. Most
of the builtin.mk files test for the presence of built-in software by
checking for the existence of certain files, e.g. <pthread.h>, and we
now assume that if that file is under ${LOCALBASE}, then it must be
from pkgsrc. This modification is a nod toward LOCALBASE=/usr. The
exceptions to this new check are the X11 distribution packages, which
are handled specially as noted below.
The third major change is providing builtin.mk and version.mk files
for each of the X11 distribution packages in pkgsrc. The builtin.mk
file can detect whether the native X11 distribution is the same as
the one provided by pkgsrc, and the version.mk file computes the
version of the X11 distribution package, whether it's built-in or not.
The fourth major change is that the buildlink3.mk files for X11 packages
that install parts which are part of X11 distribution packages, e.g.
Xpm, Xcursor, etc., now use imake to query the X11 distribution for
whether the software is already provided by the X11 distribution.
This is more accurate than grepping for a symbol name in the imake
config files. Using imake required sprinkling various builtin-imake.mk
helper files into pkgsrc directories. These files are used as input
to imake since imake can't use stdin for that purpose.
The fifth major change is in how packages note that they use X11.
Instead of setting USE_X11, package Makefiles should now include
x11.buildlink3.mk instead. This causes the X11 package buildlink3
and builtin logic to be executed at the correct place for buildlink3.mk
and builtin.mk files that previously set USE_X11, and fixes packages
that relied on buildlink3.mk files to implicitly note that X11 is
needed. Package buildlink3.mk should also include x11.buildlink3.mk
when linking against the package libraries requires also linking
against the X11 libraries. Where it was obvious, redundant inclusions
of x11.buildlink3.mk have been removed.

Release Notes for PCB snapshot 20050315
========================================================================
- Several footprint library fixes including TO-220 parse errors and
incorrect drill holes on several componenets.
- Fixed a crashing bug in the pinout window.
- Allow the FAB author to be set via an Xresource to override what
PCB might have gotten from the gecos information.
- Added table of standard drill sizes to the manual.
- Fixed a crashing bug when trying to use arrow keys to adjust the scale
slider in the print dialog box.

Release Notes for PCB snapshot 20050127
========================================================================
- Fix drill size for PLCC sockets in ~geda library. Fix drill size for
LED3 and LED5 footprints in ~geda library.
- Move the right-click popup menu to pcb-menu.res.
- Add DisperseElements() action for spreading out elements in an initial
layout.
- Fix fab drawing output for the case where a very small number of
drill sizes are used.
- Various documentation improvements.
- Remove many compiler warnings.
- Added metric output to the cursor display
- Fix <Key>. for toggling 45 degree mode.
- Crosshair snap snaps to center of pads and also to the mark of the
element.
- Protect all strcmp() calls with a check for a NULL pointer. Fixes
various crashes.
- Fixed the mode buttons which were unresponsive in some versions of
the X libraries.
- Element names may be edited over the element.
- Added --enable-efence for ElectricFence debugging. Off by default
- Added --disable-rpath to avoid using rpath for the X libraries.
- Added vendor resource file support. This allows lets you specify
a set of allowed drill sizes and drc rules for a particular vendor.
- Added -action command line option to allow executing an action on
startup.
- Date and time of compilation added to About dialog.
- Fix a bug where the soldermask relief on a new element is 100x smaller
than the default when "convert buffer to element" is used.
- Fix a name_tree corruption bug when changing an element name.
- Don't remove the formatted manual with a 'make clean' since they are
part of the distfile.
- Let automake handle the html and pdf conversion. This ends up using
texi2pdf for the pdf output which seems to do a better job than ps2pdf.
- Sort actions by modifier so that both Ctrl<Key>x and <Key>x work.
- Fix a SelectByName bug.
- Fix non-gcc compilation
- Command history added to :
- Fixed pinout window crash
- Allow Ctrl-drag to copy objects in arrow mode.
- Fixed a polygon clearance bug
- Fix an arc bounding box calculation error.

========================================================================
This has been an exciting 3 months for PCB. Many improvements have
been made in the program as well as additions and improvements to the
footprint library. Thanks to everyone who has provided feedback,
patches, etc.
----------------------
Additions/Improvements
----------------------
- Expanded DRC checking
- "Realtime" DRC checking
- DRC settings are now stored in the board fle
- Centroid (X-Y) and bill of materials output
- Dynamic menus. Users can now customize the menus via a
site-wide, per-user, or per-project menu resource file.
- Significant improvements to autorouting of congested designs.
- Autorouter can now use power planes.
- Improved appearance in autorouter output.
- Silk on pads/pins is clipped in RS-274-X output
- Ordering is preserved when writing output files so that diff
may be effectively used on pcb files.
- The autoplace feature now actually works
- Added ToggleVisibility action
- Most of the database is now kept in rtrees which avoids linear
searches. This speeds up operation significantly.
- Added SetFlag, ClrFlag, ChangeFlag actions
---------
Bug Fixes
---------
- pin/pad bounding box calculation fixed. Components can
now be placed closer to the edge of the board.
- miter trace optimization bug.

Pcb - X11 interactive printed circuit board layout system.
Pcb is a handy tool for the X Window System to design printed
circuit boards. All coordinate units are 1/1000 inch.
Please note that this package is a development snapshot and while it contains
the latest and greatest features, it may be buggy as well. There is a seperate
pcb package which is made of the stable releases.
