 Function Import-PrivilegeUtil {
     <#
     .SYNOPSIS
-    Compiles the C# code that can be used to manage Windows privileges from an
-    Ansible module. Once this function is called, the following PowerShell
-    cmdlets can be used;
-
-        Get-AnsiblePrivilege
-        Set-AnsiblePrivilege
-
-    The above cmdlets give the ability to manage permissions on the current
-    process token but the underlying .NET classes are also exposed for greater
-    control. The following functions can be used by calling the .NET class
-
-    [Ansible.PrivilegeUtil.Privileges]::CheckPrivilegeName($name)
-    [Ansible.PrivilegeUtil.Privileges]::DisablePrivilege($process, $name)
-    [Ansible.PrivilegeUtil.Privileges]::DisableAllPrivileges($process)
-    [Ansible.PrivilegeUtil.Privileges]::EnablePrivilege($process, $name)
-    [Ansible.PrivilegeUtil.Privileges]::GetAllPrivilegeInfo($process)
-    [Ansible.PrivilegeUtil.Privileges]::RemovePrivilege($process, $name)
-    [Ansible.PrivilegeUtil.Privileges]::SetTokenPrivileges($process, $new_state)
-
-    Here is a brief explanation of each type of arg
-    $process = The process handle to manipulate, use '[Ansible.PrivilegeUtils.Privileges]::GetCurrentProcess()' to get the current process handle
-    $name = The name of the privilege, this is the constant value from https://docs.microsoft.com/en-us/windows/desktop/SecAuthZ/privilege-constants, e.g. SeAuditPrivilege
-    $new_state = 'System.Collections.Generic.Dictionary`2[[System.String], [System.Nullable`1[System.Boolean]]]'
-        The key is the constant name as a string, the value is a ternary boolean where
-            true - will enable the privilege
-            false - will disable the privilege
-            null - will remove the privilege
-
-    Each method that changes the privilege state will return a dictionary that
-    can be used as the $new_state arg of SetTokenPrivileges to undo and revert
-    back to the original state. If you remove a privilege then this is
-    irreversible and won't be part of the returned dict
+    No-op, as the C# types are automatically loaded.
