Hi,
Can anyone explain how we can  add a module dependency by code. Foe example i have a module 'test_module', now it have only one dependency 'base_setup'. After install this module i need to add a depend module 'sale_management' to my module (in some action). Also it should follow the basic dependency feature, ie when i uninstall the 'sale_management' my 'test_module' also need to get uninstalled.

Thanks
