+.Nd decrypt caesar ciphers
+.Sh SYNOPSIS
+.Nm
+.Op Ar rotation
+.Nm rot13
+.Sh DESCRIPTION
+The
+.Nm
+utility attempts to decrypt caesar ciphers using English letter frequency
+statistics.
+.Nm Caesar
+reads from the standard input and writes to the standard output.
+.Pp
+The optional numerical argument
+.Ar rotation
+may be used to specify a specific rotation value.
+If invoked as
+.Nm rot13 ,
+a rotation value of 13 will be used.
+.Pp
+The frequency (from most common to least) of English letters is as follows:
+.Bd -ragged -offset indent
+ETAONRISHDLFCMUGPYWBVKXJQZ
+.Ed
+.Pp
+Their frequencies as a percentage are as follows:
+.Bd -ragged -offset indent
+E(13), T(10.5), A(8.1), O(7.9), N(7.1), R(6.8), I(6.3), S(6.1), H(5.2),
+D(3.8), L(3.4), F(2.9), C(2.7), M(2.5), U(2.4), G(2),
+P(1.9), Y(1.9),
+W(1.5), B(1.4), V(.9), K(.4), X(.15), J(.13), Q(.11), Z(.07).
+.Ed
+.Pp
+Rotated postings to
+.Tn USENET
+and some of the databases used by the
+.Xr fortune 6
+program are rotated by 13 characters.

+.Sh NAME
+.Nm cgram
+.Nd solve Sunday-paper cryptograms
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+.Nm
+is a curses-based widget for solving Sunday-paper-type cryptograms
+based on substitution ciphers.
+A random cleartext is chosen using
+.Xr fortune 6
+and a random substitution key is generated.
+.Pp
+The ciphertext is displayed.
+Typing a letter changes the key so that the letter under the cursor
+maps to the newly typed letter, and updates the display accordingly.
+Use Emacs-type cursor commands to move around.
+Enter a tilde
+.Pq ~
+to quit.
+Press asterisk
+.Pq *
+to enter an easier mode where correct letters are displayed in
+boldface.
+.Sh SEE ALSO
+.Xr caesar 6
+.Sh HISTORY
+.Nm
+was written circa 2004.
+It was imported into
+.Nx
+in 2013 and first appeared in
+.Nx 7.0 .

+.Sh NAME
+.Nm file2c
+.Nd convert file to c-source
+.Sh SYNOPSIS
+.Nm
+.Op Fl sx
+.Op Fl n Ar count
+.Op Ar prefix Op Ar suffix
+.Sh DESCRIPTION
+The
+.Nm
+utility reads a file from stdin and writes it to stdout, converting each
+byte to its decimal or hexadecimal representation on the fly.
+The byte values are separated by a comma.
+This also means that the last byte value is not followed by a comma.
+By default the byte values are printed in decimal, but when the
+.Fl x
+option is given, the values will be printed in hexadecimal.
+When
+.Fl s
+option is given, each line is printed with a leading tab and each comma is
+followed by a space except for the last one on the line.
+.Pp
+If more than 70 characters are printed on the same line, that line is
+ended and the output continues on the next line.
+With the
+.Fl n
+option this can be made to happen after the specified number of
+byte values have been printed.
+The length of the line will not be considered anymore.
+To have all the byte values printed on the same line, give the
+.Fl n
+option a negative number.
+.Pp
+A prefix and suffix strings can be printed before and after the byte values
+(resp.)
+If a suffix is to be printed, a prefix must also be specified.
+The first non-option word is the prefix, which may optionally be followed
+by a word that is to be used as the suffix.
+.Pp
+This program is typically used to embed binary files into C source files.
+The prefix is used to define an array type and the suffix is used to end
+the C statement.
+The
+.Fl n , s
+and
+.Fl x
+options are useful when the binary data represents a bitmap and the output
+needs to remain readable and/or editable.
+Fonts, for example, are a good example of this.
+.Sh EXAMPLES
+The command:
+.Bd -literal -offset indent
+date | file2c 'const char date[] = {' ',0};'
+.Ed
+.Pp
+will produce:
+.Bd -literal -offset indent
+const char date[] = {
+83,97,116,32,74,97,110,32,50,56,32,49,54,58,50,56,58,48,53,
+32,80,83,84,32,49,57,57,53,10
+,0};
