How to a Remove Distribution Point From Package using PowerShell in SCCM 2012?

Am new to Powershell, could someone tell me,  How to  Remove a Distribution Point From Package using PowerShell in SCCM 2012?

i was able to find powershell scripts to remove a package from a distribution point group on the internet but there were no entries for removing a single DP from a package.

Hope somebody out there could help.
