+.SH NAME
+passcheck - passphrase strength evaluator
+.SH SYNOPSIS
+.BR passcheck
+.IR "" [ OPTION ]...\ <
+.IR PASSPHRASE_LIST
+.SH DESCRIPTION
+Evaluates the strength of passphrases based.
+All passphrases are given a non-negative integer rating.
+.PP
+The output is formatted so that it is suitable for
+piping into \(aqsort -rn\(aq to sort passphrases by strength.
+.PP
+300 is a good threshold for strong passphrases,
+.br
+200 is a good threshold for acceptable passphrases.
+.SH OPTIONS
+.TP
+.BR \-r ,\  \-\-raw
+Treat escape sequences as part of the passphrases.
+If not used, ANSI escape sequences are ignored.
+.TP
+.BR \-w ,\  \-\-waste-ram
+Loads the blacklist into RAM and creates a hash set
+of it. It is unreasonable to do this unless you have
+the process running indefinitely and (somewhat)
+continuously feed passphrases. Note that this
+requires a lot of RAM.
+.SH RATIONALE
+Passphrase-strength meters used on the Web use horrid
+heuristics and does not even blacklist the most common
+passphrases. We need better passphrase-strength meters
+to keep users safe.
