/*
Some components need to be run at the startup of mozilla or embedding - to
start new services etc.
This interface provides a generic way to start up arbitrary components
without requiring them to hack into main1() (or into NS_InitEmbedding) as
it's currently being done for services such as wallet, command line handlers
etc.
We will have a category called "app-startup" which components register
themselves in using the CategoryManager.
Components can also (optionally) add the word "service," as a prefix
to the "value" they pass in during a call to AddCategoryEntry() as
shown below:
categoryManager->AddCategoryEntry(APPSTARTUP_CATEGORY, "testcomp",
"service," NS_WALLETSERVICE_CONTRACTID
true, true,
getter_Copies(previous));
Presence of the "service" keyword indicates the components desire to
be started as a service. When the "service" keyword is not present
we just do a do_CreateInstance.
When mozilla starts (and when NS_InitEmbedding()) is invoked
we create an instance of the AppStartupNotifier component (which
implements nsIObserver) and invoke its Observe() method.
Observe() will enumerate the components registered into the
APPSTARTUP_CATEGORY and notify them that startup has begun
and release them.
