+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
