Fabrizio,

I apologize for the tone of my 2nd to last email, I see now that it could have
been misinterpreted.  Your work is very much appreciated.  Our repo, and your
checkout, and anyone's checkout has files in it.

The *.svg files are in it.  The *.obj files and the *.o files and the *.png
files are not in it.  This is because they can be rebuilt through tools.

The *.cpp representations of the bitmaps are also already in the repo by
design.  So when creating a new bitmap, we need the *.svg file, and a PNG
MAINTAINER needs to generate the *.cpp file, and make sure both are added to the
bzr repo with:


$ bzr add <source_path>/<some>.svg  <cpp_path>/<some>.cpp


The <some>.png file is only needed temporarily to build the <some>.cpp file. 
And technically only the png maintainer who creates the <some>.cpp file ever
even sees it on his/her disk.

This is because the <some>.cpp file gets added to the repo.  This saves other
builders from having to install all the PNG MAINTAINER tools.

Normal, non PNG MAINTAINER builders can build Kicad without even having the
actual <some>.png file ever be on their disk.

And as Wayne said, as long as you set MAINTAIN_PNGS to ON, all you should have
to do to build a bitmap's *.cpp, is do a


$ make


_Only changed_   *.svg files get re-processed through the png tool flow and out
to *.cpp.

This was the whole idea about the build automation that I spent two days on. 
Two days is probably a small portion of the time you spent, so again, thanks for
your efforts.  And I certainly did not intend to de-motivate you from continuing
your effort towards perfection.  Please do continue.  We are all very appreciative.


Dick
