   8 .SH DESCRIPTION
   9 This manual page documents briefly the
  10 .B nowhere
  11 command.
  12 This manual page was written for the Debian distribution
  13 because the original program does not have a manual page.
  14
  15 The
  16 .B nowhere
  17 program is a simple source to source translation tool that expands out
  18 case expressions with conditional patterns.
  19
  20 Conditional patterns use the "where" keyword.  For example:
  21
  22  case l of
  23    [x,y,z] where x=1 => 1
  24  | _ => 2
  25
  26 means the same as:
  27
  28  case l of
  29    [1,y,z] => 1
  30  | _ => 2
  31
  32 Currently, the input file must be of the following form:
  33
  34  local
  35    <definitions>
  36  in
  37    <body>
  38  end
  39    <definitions>
  40
  41 should include all datatypes definitions that are used inside the
  42 .IR body .
  43 It is only for the tool's benefit and does not appear in the output.
  44 Only
  45 .I body
  46 appears at the output.  You can use the special declaration
  47
  48      include "filename"
  49
  50 to import extra definitions.
  51
  52 The tool translates all case expressions with guards into the appropriate code.
