obtained via some secure medium), this provides strong assurance that

+.B "\-j, \-\-junk"
+Report files whose hashes have not been checked. This is most useful in
+conjunction with
+.RB ` \-c ',
+though it's valid without. The program merely prints warnings about
+junk files when computing hashes, but will exit nonzero if any are found
+when checking them.
+.TP
.B "\-b, \-\-binary"
Assume that the files to be hashed are binary files. This doesn't make
any difference in Unix systems, although it might on other platforms
