  32 .Sh NAME
  33 .Nm cgram
  34 .Nd solve Sunday-paper cryptograms
  35 .Sh SYNOPSIS
  36 .Nm
  37 .Sh DESCRIPTION
  38 .Nm
  39 is a curses-based widget for solving Sunday-paper-type cryptograms
  40 based on substitution ciphers.
  41 A random cleartext is chosen using
  42 .Xr fortune 6
  43 and a random substitution key is generated.
  44 .Pp
  45 The ciphertext is displayed.
  46 Typing a letter changes the key so that the letter under the cursor
  47 maps to the newly typed letter, and updates the display accordingly.
  48 Use Emacs-type cursor commands to move around.
  49 Enter a tilde
  50 .Pq ~
  51 to quit.
  52 Press asterisk
  53 .Pq *
  54 to enter an easier mode where correct letters are displayed in
  55 boldface.
  56 .Sh SEE ALSO
  57 .Xr caesar 6
  58 .Sh HISTORY
  59 .Nm
  60 was written circa 2004.
  61 It was imported into
  62 .Nx
  63 in 2013 and first appeared in
  64 .Nx 7.0 .
