 # loncapaverifypackages
 
+# This tool helps with system verification.  It looks at the
+# RPM packages on the system.  It downloads a list of expected
+# RPMs from install.lon-capa.org.  It makes two comparisons.
+# Which packages are missing?  Which packages are unexpected?

+LON-CAPA system, or malicious activity.  You may want to remove or upgrade these.
