custom post-install hook for specific package?

[Tomas Zatko <tomas.zatko@gmail.com>]

Hi guys

I would like to ask if there is any simple and clear way to make custom
post-install hook for specific distribution package.
I need to run custom script after unattended upgrade of php. This script
will recompile eaccelerator.
Thank you

Best regards
