Reading a text file for users to get-adprincipalgroupmembership

[Erik_Mullins]

I would like to have powershell read a list of users (text file is fine) and perform 

Get-ADPrincipalGroupMembership UserName | Select Name
 for each user.  Ideally I would like this to be | Export-CSV with each user in its own column and groups listed underneath.  However I will take anything I can get at this point as long as I can tell what groups belong to which user.  I have tried Get-content and tried to pass that to an object or variable without any luck.  I hope you can assist me because I have a rather large project on my hands and this part of the project is slightly time consuming and I think PS can help but dont know how.
