-
-For TFILEPtr. Use TIFStream or TOFStream if you need IO. For some rare use cases a TFileMap might also do.
-
-For fput/fget/getline. Use streams API.
-
-For struct ffb and struct prnstr. Just don't use them. Even if you can figure out what they do.

-/** This file currently implements creation of mappable read-only hash file.
-    Basic usage of these "static hashes" is defined in util/static_hash.h (see docs there).
-    Additional useful wrappers are available in util/static_hash_map.h
-
-    There are two ways to create mappable hash file:
-
-    A) Fill an THashMap/set structure in RAM, then dump it to disk.
-       This is usually done by save_hash_to_file* functions defined in static_hash.h
-       (see description in static_hash.h).
-
-    B) Prepare all data using external sorter, then create hash file straight on disk.
-       This approach is necessary when there isn't enough RAM to hold entire original THashMap.
-       Implemented in this file as TStaticHashBuilder class.
-
-       Current implementation's major drawback is that the size of the hash must be estimated
-       before the hash is built (bucketCount), which is not always possible.
-       Separate implementation with two sort passes is yet to be done.
-
-       Another problem is that maximum stored size of the element (maxRecSize) must also be
-       known in advance, because we use TDatSorterMemo, etc.

-    That saved object is accessed via pointer to sthash object (that must have
-    the same parameters as original THashMap object)
-
-    If either key or value are variable-sized (i.e. contain pointers), user must
