Get programmatically User Roles and Permissions in SSRS 2008 - security

Question

I use SSRS 2008 on Windows 2008 R2.
How can I get the user list of roles and permissions (Reports Manager Roles such as Browser, Content Manager, etc) using Powershell or C# (programmatically)?
Any suggestions ?
Notes:
"Folder Settings" area where you can specify roles for a user - "Content Manager," "Publisher," "Browser," "Report Builder," and "My Reports"
SSRS has 2 security/role sections available in the web GUI: Folder Settings and Site Settings.

I try with my script powershell.
