-// Apps may define commands using Registry entries. There are two supported
-// formats:
-//
-// Legacy Format:
-// ROOT\\Software\\Google\\Update\\Clients\\{app-guid}
-//   <command-id> = REG_SZ (command line)
-//
-// New Format:
-// ROOT\\Software\\Google\\Update\\Clients\\{app-guid}\\Commands\\<command-id>
-//   CommandLine   = REG_SZ
-//   SendsPings    = DWORD
-//   WebAccessible = DWORD
-//   ReportingId   = DWORD
-//
-// Only the command line is required, all other values default to 0. It is not
-// possible to set other values using the Legacy format.
