 .SH DESCRIPTION
 
-Hru takes any whole number in the standard input and, to the standard output,
-prints the equivalent number in the most human-readable unit defined by the 
-International System of Units.
+Hru reads byte counts in the form of whole numbers from the standard input and
+writes to the standard output the same number converted one of the units of data
+defined by the International System of Units.
+
+The program will convert the byte count to the highest unit possible where the
+value is greater than one.

 The GNU project’s ls(1) implementation contains a human-readable option (-h)
 that, when specified, makes the tool print size information in a format more
-immediately readable. This functionality is not useful only in the context of
+immediately readable. This functionality is useful not only in the context of
 ls(1) so the decision was made to split it into a new tool. The original
 functionality in GNU’s ls(1) can be emulated with fop(1) combined with this
 program.
