+# 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.
