a) create a new nsIComponentManager with only four functions on it: CreateInstance CreateInstanceByContractID GetClassInfo GetClassInfoByContractID. b) rename the old nsIComponentManager to nsIComponentManagerObsolete. c) fixes callers which use to access the nsIComponentManager for component registration functionality. These callers will temporary use the nsIComponentManagerObsolete interface. d) Create a new API NS_GetComponentManager() which mirrors the NS_GetServiceManager() e) Perserves the old NS_GetGlobalComponentManager(). Note the cast usage. r/sr = rpotts@netscape.com alecf@netscape.com brendan@mozilla.org
