I've put up some more documents about the build process on
http://www.cruzers.com/~rfm
These are essentially the same as what I have posted to ib-build.

The documents are:
http://www.cruzers.com/~rfm/ibbuild-unix-overview.txt
An overview of how the unix builds are supposed to work.

http://www.cruzers.com/~rfm/metedata_gdb.txt
What is yachts/metadata.gdb

http://www.cruzers.com/~rfm/msgs-overview.txt
Ultra high level description of why we have msg.gdb and what codes.e
is supposed to do.

http://www.cruzers.com/~rfm/ibbuild-win32.txt
instructions for building under windows.

Please address specific corrections to me (rfm@...)
General discussion of the build process should go to
mers.interbase.build, AKA the ib-build mailing list.
