+.SH NAME
+zerofill \- clear unused disk space and blank devices.
+.SH SYNOPSIS
+.B zerofill
+.RI [ options ]
+.RI [ devices ]
+.I ...
+.br
+.SH DESCRIPTION
+This command is a relative of nullfile. Like nullfile, it can be used
+to write all unused disk space with '0', thereby making file systems that
+are stored on virtual machines easier to pack. In addition, zerofill can
+fill unused disk space with random data before zeroing, which can be useful
+to remove forensic trace of deleted files. Finally, zerofile can be told
+to operate on and zero (erase) complete disk devices.
+.SH OPTIONS
+.TP
+.BI \-\-random= count
+Number of passes to use writing random data before wiping data.
+.TP
+.B \-\-help
+Outputs help screen for the user.
