=head1 NAME

App::Pinto::Command::log - show the revision logs of a stack

=head1 VERSION

version 0.091

=head1 SYNOPSIS

  pinto --root=REPOSITORY_ROOT log [STACK] [OPTIONS]

=head1 DESCRIPTION

!! THIS COMMAND IS EXPERIMENTAL !!

This command shows the commit logs for the stack.  To see the precise
changes in any particular commit, use the L<App::Pinto::Command::show>
command.

=head1 COMMAND ARGUMENTS

As an alternative to the C<--stack> option, you can specify it as
an argument.  So the following examples are equivalent:

  pinto --root REPOSITORY_ROOT log --stack=dev
  pinto --root REPOSITORY_ROOT log dev

A C<stack> argument will override anything specified with the
C<--stack> option. If the stack is not specified using neither 
argument nor option, then the logs of the default stack will 
be shown.

=head1 COMMAND OPTIONS

=over 4

=item --stack NAME

=item -s NAME

Show the logs of the stack with the given NAME.  Defaults to the name
of whichever stack is currently marked as the default stack.  Use the
L<stacks|App::Pinto::Command::stack> command to see the stacks in the
repository.
