+Hostsblock is a bash script for Linux designed to take advantage of the
+/etc/hosts file to provide system-wide blocking of internet advertisements,
+malicious domains, trackers, and other undesirable content. To do so, it
+downloads a configurable set of blocklists and processes and their entries into
+a singular file.
+
+The SlackBuild assumes that dnsmasq is not available so it will configure
+hostsblock to overwrite the current /etc/hosts file. The install script will
+backup the current /etc/hosts file to /etc/hostsblock/hosts.head if it does
+not already exist.
+
+After uninstalling hostsblock, you should copy hosts.head back to /etc/hosts.
+
+To have hostsblock automatically update /etc/hosts once a week, run:
+  ln -sf /usr/sbin/hostsblock /etc/cron.weekly/hostsblock

+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
