-// A library to manage RLZ information for access-points shared
-// across different client applications.
-//
-// All functions return true on success and false on error.
-// This implemenation is thread safe.
-//
-// Each prototype mentions the registry access requirements:
-//
-// HKLM read:  Will work from any process and at any privilege level on Vista.
-// HKCU read:  Calls made from the SYSTEM account must pass the current user's
-//             SID as the optional 'sid' param. Can be called from low integrity
-//             process on Vista.
-// HKCU write: Calls made from the SYSTEM account must pass the current user's
-//             SID as the optional 'sid' param. Calls require at least medium
-//             integrity on Vista (e.g. Toolbar will need to use their broker)
-// HKLM write: Calls must be made from an account with admin rights. No SID
-//             need be passed when running as SYSTEM.
-// Functions which do not access registry will be marked with "no restrictions".

-// Testing RLZ requires reading and writing to the Windows registry.  To keep
-// the tests isolated from the machine's state, as well as to prevent the tests
-// from causing side effects in the registry, HKCU and HKLM are overridden for
-// the duration of the tests. RLZ tests don't expect the HKCU and KHLM hives to
-// be empty though, and this function initializes the minimum value needed so
-// that the test will run successfully.
-//
-// The two arguments to this function should be the keys that will represent
-// the HKLM and HKCU registry hives during the tests.  This function should be
-// called *before* the hives are overridden.
