gEDA-user: ANN: gerbv-0.16 released

[Stefan Petersen <spe@stacken.kth.se>]

Bueono vistas!

It is time for one more of the more and more randomly releases of gerbv.
This is the sixteenth release of the Free Gerber Viewer, aka gerbv,
the "projects-r-us" release.

This time it's not so many bugs found, but a big bunch of features added.
Notably are:
* projects: you can save and load setups in what I call projects.
* GTK+ 2 support: Compiles under GTK+ 2 with the added benfit of
  `ldd gerbv|wc -l` now returns 24 instead of 14. ;-)
* Now you can invert a layer by the push of button. Basically.
* When gerber files were defined with omit trailing zeros, gerbv could
  parse them very bad. Now it should work better.
* Aperture macros did not handle exposures at all. Now they do a better
  work.  Some thermals are defined from their CAD program as a sequence of
  aperture macros instead of just using aperture macro 7. They are drawn
  better now.
* Handles tool tables when drawing drill files thanks to Dimitri. See man
  page for more info.

Projects
If you load a bunch of files, sort them into a nice order and give them
nice colors, you can now save this setup and recall it at a later time.
The project file format is in Scheme and for this purpose I have
incorporated a Scheme interpreter called TinyScheme. The casual user
shouldn't note this but the advanced user can probably do cool stuff with
it.

The project stuff is very untested and I actually don't know how people
will use it. Try it out and send me your suggestions for improvements. The
main question is how paths should be handled. How it is intended to work
is described in the man page. Thanks Dan for testing it out.

Why bring in a complete Scheme interpreter when all you need is a simple
resource file parser? Because I could. And I missed it since I threw
Guile out head over heels.

GTK+ 2 support
This was a necessary step for me, because when more and more distributions
switch over to gnome2/gtk2 I didn't want to be left behind. There are
still some quirks around this, so you have to enable it at configure time.

I have in one instance used GTK_ENABLE_BROKEN to get around stuff
deprecated in GTK+ 2 (see log.c).

Thanks to all patchers and error reporters.

If there is anyone out there wanting to hack and develop gerbv further,
please step forward.

This release has many new features so expect bugs. If you find anything,
please report them asap. There are currently a couple of known bugs (see
the buglist on gerbv sourceforge site), but I do this release anyhow. I
get patches with respect to previous, and this version and previous starts
to differ too much to be really good.

Homepage for gerbv is still http://gerbv.sourceforge.net/ where a bug
database, a feature request database, the CVS and a commit mailinglist is
available.

To download gerbv goto
        http://prdownloads.sourceforge.net/gerbv/
and grab gerbv-0.16.tar.gz

To install the program do
1. gzip -dc gerbv-0.16.tar.gz | tar xf -
2. cd gerbv-0.16
3. ./configure
4. make install

Interesting configure options are:
--help              : Lists all options
--disable-exportpng : Disable compilation of export of PNGs
--enable-gtk2       : Compile with GTK+ 2 instead of GTK+ 1
--prefix=<dir>      : Install from dir <prefix>
--with-maxfiles     : Set maximal number of files (default 20).
--enable-unit-mm    : Change default unit in status bar to mm from inch.
