class app {
exec { "prescript":

package { package1: ensure => installed, require => Exec["prescript"],
notify => Exec["postscript"] }
package { package2: ensure => installed, require => Package["package1"],
notify => Exec["postscript"] }
# or require the exec if ordering doesn't matter
..
exec { "postscript":
command => "post install",
refreshonly => true,
}
}
Not 100% sure that the require will run the prescript, but I think that is
correct. And the postscript will get run once at the end (even though it is
notified 4 times)
