+Ksplice allows system administrators to apply patches to their
+operating system kernels without rebooting.  Unlike previous hot
+update systems, Ksplice operates at the object code layer, which
+allows Ksplice to transform many traditional source code patches into
+hot updates with little or no programmer involvement.  In the common
+case that a patch does not change the semantics of persistent data
+structures, Ksplice can create a hot update without a programmer
+writing any new code.

+# 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 ':'.
