Get corresponding INCLUDES of subroutines

Hi,

I have a list of subroutines, which are invoked during Payroll execution. I wanted to know the corresponding Packages where the Subroutines belong to.

For accomplishing the above task, I guess the way would be to find the corresponding INCLUDES of Subroutines, and then find the Packages where the INCLUDE resides.

Can anyone help with a table name or program which maps Subroutines to Includes and Package
