+Version 1.1 now supports increasing the key using the fh_replace*
+functions.  Previously it would simply return NULL when you tried to
+increase the key.  It also improves performance slightly by only calling
+checkcons when we are about to use it, at extract, instead of calling it
+on every insert.
+
+I have now fixed fh_union and it properly updates the minimum.
+
+Thanks to Ryan Earl for pointing out that in fh_consolidate, it is VERY
+time consuming to constantly malloc/free an array of pointers.  The array
+is small enough that simply reallocating when more pointers are needed
+is ok.
+
+Thanks to Thomas Eschbach and Wolfgang Guenther who have pointed out bugs
+with my code.  Wolfgang Guenther provided a fix which put in on the correct
+track for where the bug was.  They have also provided a few test programs
+that exhibited other bugs which I have now integrated into my source so
+that you can easily regress test the library.
+
+I have reciently completed a review of the code.  I have made a number
+of improvements with a few minor interface changes.  There is another
+improvement to the rh_replace* family of functions to help eliminate
+redundant code.
+
+I'm still planning on writing a type safe memory allocator for use with
+the code instead of using malloc to hopefully improve performance slightly.

+These functions are shared between both key heaps and normal heaps.
+.PP
+Once a

+.BR fh_delete (3)
+that
+.B elem
+pointer may be reused to store another datum.
+You should make sure that you destroy any copies of the pointer.
+.SH RETURN VALUES
+The
+.B fh_extractmin
+function returns the value of
+.B data
+that is the minimum element and removes it from the heap.
+.PP
+The
+.B fh_min
+function returns the current minimum element but does
+.I not
+remove it from the heap.
+.PP
+The
+.B fh_replacedata
+replaces the data in
+.B elem
+and returns the old data.
+.PP
+The
+.B fh_delete
+function removes
+.B elem
+from the heap, and returns the
+.B data
+that was stored in the element.
+.PP
+The
+.B fh_deleteheap
+complete destroys the heap.  It does not free any user supplied
+.B data
+elements stored in the heap.
+.PP
+The
+.B fh_union
+function returns the union of the two heaps

+.PD
+.SH DESCRIPTION
+The
+.B fh_makekeyheap
+function makes a Fibonacci heap which does ordering based on an
+integer key that is given in addition to the data.
+This menthod is useful so that you can eliminate the need to call
+a comparision function to order the data in the heap.
+.PP
+The pointer to the structure
+.B fibheap
+returned by
+.B fh_makekeyheap
+is an opaque structure.  The the pointer can only be passed to other
+functions in the
+.B libfib
+library.
+.PP
+The
+.B fh_insertkey
+function inserts the
+.B data
+element into the heap with a value of
+.BR key .
+The pointer returned can be used in calls to functions like
+.BR fh_delete (3)
+to delete the key from the heap before it gets extracted via
+.BR fh_extractmin (3).
+.SH RETURN VALUES
+The
+.B fh_makekeyheap
+function returns a pointer to a heap structure used to insert and extract
+data elements.
+.PP
+The
+.B fh_insertkey
+functions returns a pointer to a heap element structure which can be used
+to manimulate that data element in the heap.
+.PP
+The
+.B fh_minkey
+function returns the integer key of the data at the top of the heap.  If you would like to view the data, see
+.BR fh_min (3).
+.SH SEE ALSO
+.BR fh_extractmin (3)
+.SH AUTHORS
+This library and man page was writen by John-Mark Gurney <gurney_j@efn.org>.
+.SH BUGS
+A key heap does not provide a way for handling key collitions and deffering
+decission to a user provided function to resolve colissions.
