+
+This module defines any memory handler to be used by libwww for allocating
+and de-allocating dynamic memory. As dynamic memory may be a scarce resource,
+it is required that an application can handle memory exhaustion gracefully.
+This module provides an interface that covers the following situations:
+
+
+ o
+ Handling of allocation, reallocation and de-allocation
+ of dynamic memory
+ o
+ Recovering from temporary lack of available memory
+ o
+ Panic handling in case a new allocation fails
+
+
+Note: The Library core provides a default set of memory handlers
+for allocating and de-allocating dynamic memory. In order to maintain a
+reasonable performance, they are not registered dynamically but assigned
+using C style macros. Hence, it is not possible to swap memory handler
+at run time but this was considered to be a reasonable trade-off.
+
+This module is implemented by HTMemory.c, and it
+is a part of the W3C Sample Code
+Library.

+ Memory Freer Functions
+.
+
+The dynamic memory freer functions are typically functions that are capable
+of freeing large chunks of memory. In case a new allocation fails, the allocation
+method looks for any registered freer functions to call. There can be multiple
+freer functions and after each call, the allocation method tries again to
+allocate the desired amount of dynamic memory. The freer functions are called
+in reverse order meaning that the last one registered gets
+called first. That way, it is easy to add temporary freer functions
+which then are guaranteed to be called first if a methods fails.
+(
+ Add a Freer Function
+)
+
+You can add a freer function by using the following method. The Library may
+itself register a set of free functions during initialization. If the application
+does not register any freer functions then the Library looks how it can free
+internal memory. The freer function is passed the total number of
+bytes requested by the allocation.

+the application must have an organized way of closing down. This is done
+using the panic handler. In the libwww, each allocation is tested and
+HT_OUTOFMEM is called if a NULL was returned.
+HT_OUTOFMEM is a macro which by default calls
+HTMemory_outofmem() but of course can point to any method. The
