-MG4J (Managing Gigabytes for Java) is a collaborative effort aimed at providing
-a free Java implementation of inverted-index compression techniques; as a
-by-product, it offers several general-purpose optimised classes, including fast
-&amp; compact mutable strings, bit-level I/O, fast unsychronised buffered
-streams, (possibly signed) minimal perfect hashing for very large strings
-collections, etc.
