 // latter may be initialized early during process startup and then shared with
 // other modules in the process. For example, chrome_elf creates the instance
 // for a Chrome process and exports a GetInstallDetailsPayload function used by
 // chrome.exe and chrome.dll to create their own module-specific instances
 // referring to the same underlying payload. See install_modes.h for a gentle
 // introduction to such terms as "brand" and "mode".
