"List of providers of information about symbols.
Each element has the form (NAME TESTFUN DESCFUN) where:
NAME is a string naming a category of object, such as \"type\" or \"face\".
TESTFUN is a predicate which takes a symbol and returns non-nil if the
symbol is such an object.
DESCFUN is a function which takes three arguments (a symbol, a buffer,
and a frame), inserts the description of that symbol in the current buffer
and returns that text as well.")
