=head1 NAME
App::Pinto::Command::revert - revert stack to a prior revision
=head1 VERSION
version 0.0994_01
=head1 SYNOPSIS
  pinto --root=REPOSITORY_ROOT revert [OPTIONS] [STACK] [REVISION]
=head1 DESCRIPTION
This command creates a new revision that reverts the stack to a prior
revision.
=head1 COMMAND ARGUMENTS
The arguments are the name of the stack and/or the id of the revision to
revert to.  If the revision id is not specified, it defaults to the immediate
parent of head revision of the stack.  If the stack is not specified, then it
defaults to whichever stack is currently marked as the default.  The stack can
also be specified using the C<--stack> option.  Some examples:
  pinto ... revert                   # Revert default stack to previous revision
  pinto ... revert af01256e          # Revert default stack to revision af01256e
  pinto ... revert mystack af01256e  # Revert mystack to revision af0125e
=head1 COMMAND OPTIONS
=over 4
=item --dry-run
Go through all the motions, but do not actually commit any changes to the
repository.  At the conclusion, a diff showing the changes that would have
been made will be displayed.  Use this option to see how upgrades would
potentially impact the stack.
=item --force
Force reversion even if the revision is not actually an ancestor.  Normally,
you can only revert to a revision that the stack has actually been at.
=item --stack=NAME
=item -s NAME
Peform reversion on 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::stacks> command to see the stacks in the
repository.  This option is silently ignored if the stack is specified as a
command argument instead.
