# The purpose of this version of tupkgupdate is to avoid
# doing as much time and machine-intensive work as the full
# tupkgupdate does, by relying on the state of the mysql
# database to be correct. Since it usually is, this is a
# good means for effecting updates more quickly, and won't
# be a processor hog.
#
# Note that this version CANNOT HANDLE deleted packages. Those
# will have to be processed less frequently. The only way to
# know a package for sure is missing is to look through all
# the PKGBUILDs which is what we're trying to avoid.
