Attention une mise à jour du service Gitlab va être effectuée le mardi 18 janvier (et non lundi 17 comme annoncé précédemment) entre 18h00 et 18h30. Cette mise à jour va générer une interruption du service dont nous ne maîtrisons pas complètement la durée mais qui ne devrait pas excéder quelques minutes.

    rewrite the command line treatment to provide reasonable · 77f29212

    default actions in case explicit options are missing.
    
    The command line has the following structure:
        
        why [options] [[file|-] [-t <theory> [-g <goal>]...]...]...
    
    Summary:
        
        Qualified theories come from the library, not from file.
        When the driver is not specified, pretty-print theories.
        When neither --prove nor --output are given, print tasks.
        When no theory is specified for a file, use every theory.
        When no goal is specified for a theory, use every goal.
    
    Examples:
    
        % why.opt
        [shows usage information]
    
        % why.opt test.why
        [prints the contents of test.why]
    
        % why.opt -t int.Int
        [prints the library theory int.Int]
    
        % why.opt -D drivers/z3.drv test.why
        [sends every task from test.why to stdout]
    
        % why.opt -D drivers/z3.drv -o directory test.why
        [creates ./directory/ if it's does not exist and
         sends every task to a separate file in ./directory/]
    
        % why.opt -D drivers/z3.drv --prove test.why -t ThA
        [calls the prover for every goal from theory ThA in test.why]
    
        % why.opt -D drivers/z3.drv --prove test.why -t ThA -g G1 -g G2
        [calls the prover for G1 and G2 from theory ThA in test.why]
    
        % why.opt -D drivers/z3.drv -t int.Abs -g G1 test.why -t ThA
        [prints G1 from int.Abs and every goal from ThA in test.why]
