=head1 NAME

rt-attributes-editor - edit the content of an attribute 

=head1 SYNOPSIS

    # edit the Perl dump of attribute 2's content
    rt-attributes-editor --id 2

    # edit the dump of attribute 2's content (hash key: Query)
    # note: this will error if the attribute content is not a hashref
    rt-attributes-editor --id 2 --key Query

=head1 DESCRIPTION

This script deserializes and puts the content of an attribute defined
by <attribute id> into the preferred editor set in C<$EDITOR>. May be
useful for developers to editing attributes by hand if there is any
trouble editing it from the UI.
