=head1 NAME

Mafia - easily moderate Mafia games

=head1 SYNOPSIS

  #!/usr/bin/perl -w
  use Mafia;

  player 'Banana Bob', cop, town;
  player 'Dragon Phoenix', vanilla, townie;
  player 'Gammie', mafia, goon;
  player 'gslamm', vanilla, townie;
  player 'Untrod Tripod', mafia, goon;
  player 'Werebear', vanilla, townie;
  player 'willows_weep', town, doctor;

  day;
  lynch 'Untrod Tripod';

  night;
  factionkill 'Gammie', 'willows_weep', 'shot';
  copcheck 'Banana Bob', 'gslamm';

  day;
  lynch 'Gammie';

  night;

=head1 DESCRPTION

Mafia.pm is a Perl extension for easily moderating Mafia games. You don't even need to know Perl to use it (see L<"WHAT YOU NEED TO KNOW"> for details).

=head1 WHAT YOU NEED TO KNOW

A typical script starts with the following two lines

  #!/usr/bin/perl -w
  use Mafia;

The rest of the script is a series of function calls that describe the players and their actions.

A function call looks like this:

  function_name first_argument, second_argument, ...

Each argument is either a number, a string (which is a sequence of characters between single or double quotes, such as C<'badguy'>, C<'qwrf'>) or a constant (such as C<mafia>, C<vanilla>, C<bulletproof>).

Example calls:

  player 'Somebody', mafia, goon; # player is the function, 'Somebody' is a string, mafia and goon are constants.
  lynch 'Nobody'; # lynch is the function, 'Nobody' is a string.
  day; # day is the function. There are no arguments.

=head1 FUNCTIONS

=over

=item B<player> I<name>, I<trait>, ...

Defines a new player named I<name> and its traits (role, faction, role modifiers).

Roles: C<vanilla, goon, doctor, vigilante, roleblocker, jailkeeper, gunsmith, tracker, watcher, bodyguard, rolecop, cop, sk, hider>.

Factions: C<mafia, town>. C<townie> is a synonim for C<town>.

Other attributes: C<miller, godfather, weak, macho, bulletproof>

These traits may be specified in any order.

Example usage:

  player 'alice', town, bulletproof, miller, vigilante; # Alice is a NK-Immune Miller Vig
  player 'bob', town, weak, doctor; # Bob is a Town Weak Doctor
  player 'eve', mafia, godfather, goon; # Eve is a Mafia Godfather

=item B<day>

Defines the start of a new Night. All actions in the previous Day are now resolved.

=item B<lynch> I<player>

Notes that I<player> was lynched.

=item B<factionkill> I<killer>, I<player>, I<flavour>, [ strong => 1 ]

Notes that I<killer> killed I<player> with flavour I<flavour>. Append C<< strong => 1 >> if the kill should ignore roleblocks and doctor/jailkeeper protections. Use this for mafia kills.

Example usage:

Example usage:

  vig 'chuck', 'bob', 'shot';
  vig 'chuck', 'bob', 'shot seven times', strong => 1; # This is a Juggernaut (Strongman Vigilante) kill

=item B<roleblock> I<roleblocker>, I<player>

Notes that I<roleblocker> roleblocked I<player>.

=item B<jailkeep> I<jailkeeper>, I<player>

Notes that I<jailkeeper> roleblocked and protected I<player>.

=item B<guncheck> I<gunsmith>, I<player>

Notes that I<gunsmith> checked if I<player> has a gun.

	442	=head1 DESCRPTION
	443
	444	Mafia.pm is a Perl extension for easily moderating Mafia games. You don't even need to know Perl to use it (see L<"WHAT YOU NEED TO KNOW"> for details).
	445
	446	=head1 WHAT YOU NEED TO KNOW
	447
	448	A typical script starts with the following two lines
	449
	450	#!/usr/bin/perl -w
	451	use Mafia;
	452
	453	The rest of the script is a series of function calls that describe the players and their actions.
	454
	455	A function call looks like this:
	456
	457	function_name first_argument, second_argument, ...
	458
	459	Each argument is either a number, a string (which is a sequence of characters between single or double quotes, such as C<'badguy'>, C<'qwrf'>) or a constant (such as C<mafia>, C<vanilla>, C<bulletproof>).
	460
	461	Example calls:
	462
	463	player 'Somebody', mafia, goon; # player is the function, 'Somebody' is a string, mafia and goon are constants.
	464	lynch 'Nobody'; # lynch is the function, 'Nobody' is a string.
	465	day; # day is the function. There are no arguments.
	466
