 .SH "DESCRIPTION"
 
-\fBdus\fP is a command line utility to sort files and directories
-according to their size. It computes the said size by summing
-recursively exact file sizes through directories.
+\fBdus\fP lists files and directories according to their size. It
+computes the said sizes by summing recursively exact file sizes
+through directories. If a directory has its name appended with '/', it
+is not listed, but the elements it contains are. If no files or
+directories are provided as arguments, the current directory is used
+as default.
