NAME
deal - bridge hand generator SYNOPSIS
deal [ -ltv ] [ -e expr ] [ -i condition file ] [ -I format ] [ -s seed ] [ -[NSEW] hand-spec ] [ count ] DESCRIPTION
deal is a program to generate bridge hands. OPTIONS
-l Write deals in a "single-line" format. -t Print distribution table and exit. The distribution table is an ordered list of all possible hand patterns for a single hand. -v Be verbose, print sample count. -e expr Evaluate the Tcl expression expr. -i condition file File that defines the hand type to generate or the output format. (Can be given multiple times.) -I format Read hands from stdin. Formats available are: ddline, giblib, line, pbn, smartstack. You might deal, say, 10,000 hands which sat- isfy specific criteria, saving them to a file. Then you can use that output for input with deal -I to find out which hands satisfy other constraints. -s seed Initialize random generator with seed. -[NSEW] hand-spec Specifies the cards held by the specified hand. The hand-spec should be of the form: "AK8532 - KQ72 A65". Voids must be represented with a '-' character. hand-spec should be one argument, so the string should be quoted on the command line. count Number of hands to generate, default is 10. SEE ALSO
