+The org.lcsim.units.clhep package is a straightforward port of the
+header files in the Units include directory of CLHEP 2.0.3.0.
+<p>
+
+<p>
+The @link SystemOfUnits class defines the CLHEP numerical system of
+units, including length, energy, and so forth.
+</p>
+
+<p>
+The @link PhysicalConstants class defines commonly used physical
+constants, such as Avogadro's number, the speed of light, etc.
+</p>
+
+<p>
+<b>TODO</b> - We need to check whether the CLHEP license is open
+source or pseudo open source. I could not find a license file in the
+CLHEP distribution.
