Nicholas,
I never did anything with the DB packages. Chuck sent them to me and I sat
on them... that's about it. I never had anytime to actually do anything
with them. I think Chuck was doing the same thing that I do in his quote
below, namely, talking someone up in public about the great things that they
are going to do, as if they had already done them, so that they get a little
kick in the butt to start doing those great things :) Alas, the kick wasn't
big enough. :)

> Gerrit Haase and I will be submitting various versions of the
> Berkeley DB for inclusion into the cygwin distribution. We begin
> with the Berkley DB2, which is the first major revision of the
> original Berkeley DB. The version of db-2 is 2.7.7, which is the
> last stable version released for the db-2 line. There are many
> projects which can use the db-2, one such project being xemacs.
> Our intent is to provide the standard database api's in the same
> manner as redhat does, by partitioning the libraries in their own
> directory based on revision number. Post-install will then
> create symbolic links to the most current version. Previous
> versions can be specified by explicitly declaring the path to the
> particular version's directory or explicitly linking to that
> version. For example "-L/usr/lib/db2 -ldb" or "-ldb2". The
> packages for db-2 are based on packaging method #2 and were done
> originally by Charles Wilson and Harold Hunt. We have
> volunteered to maintain them for them, as they have other
> projects to work on. The packages have been split up into the following:
>
> db2 - core db2
> libdb2 - db2 runtime
> libdb2-devel - db2 development libraries and utilities
>
> Why this was done is best explained by Chuck, who explained it to me as:
>
> "It's a bit confusing, true -- but it came about in an evolutionary
> process while Harold and I were refining the db2 and db3.3 packages.
> Perhaps they are the tonsils or appendices of the evolutionary
> progression; it isn't clear yet.

> The idea was this: db2-devel MUST contain docu on the utilities it
> provides. Also, since the database manipulation programs are version
> specific (that is, if you have a db2 database, you MUST use
> db2_checkpoint and db2_archive on it; if all you have is
> db3.3_checkpoint, then you're up a creek). So, these utility programs
> must be able to coexist with newer versions -- hence, they are named
> "db2_foo" (with symlinks db_foo pointing to them) and they are part of
> the db2-devel package NOT the db package. [otherwise, they'd get
> replaced when you update 'db']. This way, the unversioned symlinks
> point to the most-recently-installed utilities, but the versioned
> utilities are there "forever" -- along with their documentation.
>
> It's just bad luck that once you pull out the runtime libs and put them
> into fooVER, pull out the utility programs, link libs, and headers and
> put them into fooVER-devel, all that's left behind in foo is
> documentation.

> If there were, for instance, example programs (NOT versioned utilities)
> and sample databases, then those would probably go into foo. (because
> "examples" are really only meaningful for the "current" version. Who
