# --db --rebuildflatdb db() rebuildflatdb()
# The goal here is to save some time by just updating the database rather
# than rebuilding it. Generally, though, swim -i <package> would be the
# favorable way of doing this, and ultimately may become the primary way of
# setting up the databases after the required packages for this program are
# set-up. This is because --db has to check the status file, whereas -i
# uses statusindex.db, and grabs package information right from the
# package, there are exceptions to this, certain things like the status
# will have to be found from the status file or some other method.
sub db {
# Well, we better check for any changes in the status file, before we
# attempt anything. This is made easy by the version reference hash created
# when --initdb or --rebuilddb is run, and then comparing this to the new
# results when --db is run. Only then will we process, add, and remove
# packages when we know what is gone, and what is new (whether its a
# new package name, or a package with a new version or older version).
# The statusindex.deb could be used for version checking, instead the
# important status field is compared, so if we have situations like
# "deinstall ok config-file" this will be recognized as a CHANGE. The
# update takes place so that the status field remain proper.

# referenced and checked for changes, but it's probably no saving of
# time, so first remove information from the same package of a
# different version, then add the information about the package of the
# new version (older or newer)

# packagenameSUG, packagenameCON, packagenameCONF. delete package ->
# version.
#
# for fileindex.deb -
# Find all files and directories associated with the package. Delete
# these files (keys). Find all directories where the file
# exists..delete package name from value, delete whole key if it is the
# only package name.
#
# for groupindex - delete package name (value) from Section
# it belonged to..humm, find section package belongs to in
# statusuindex.deb, and delete whole Section key if only one.
#
# for statusindex.deb -
# delete package -> version group.
#
# for flat files dirindex and searchindex -
# the removal of files and/or directories can be put on hold, and
# done with an option at a later time, since fileindex.deb remembers
# current state, at a later time the old state of the flat files can be
# compared to the new state of fileindex, and these files can be
