+ATOP is an advanced interactive monitor for Linux-systems
+to view the load on system-level and process-level.
+
+Some features depend on the 'acct' (BSD accounting) package from 
+Slackware being installed.  To enable it, execute the following:
+  touch /var/log/pacct
+  chgrp utmp /var/log/pacct
+  chmod 640 /var/log/pacct
+  accton
+
+You may want to have atop start at boot; to do so, added the
+following lines to /etc/rc.d/rc.local:
+  # Start the accounting top service
+  if [ -x /etc/rc.d/rc.atop ]; then
+    /etc/rc.d/rc.atop
+  fi

+# HOW TO EDIT THIS FILE:
+# 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 ':'.
