Retrieve file fragmentation information under Linux This package provides a simple wrapper around the Linux FIEMAP ioctl. It can be used to retrieve the list of all the extents of any given file, i.e. the area of the disk where the file is actually stored. This is similar to the filefrag command line tool provided by the e2fsprogs package.

Predicate Abstraction-based Horn-Clause/Implication Constraint Solver This package implements an SMTLIB based Horn-Clause/Logical Implication constraint solver used for Liquid Types. The package includes:
- Types for Expressions, Predicates, Constraints, Solutions
- Code for solving constraints
- A Z3 (http://z3.codeplex.com) or CVC4 (http://cvc4.cs.nyu.edu) binary.

Liquid Types for Haskell This package provides a plugin to verify Haskell programs. But most likely you should be using the liquidhaskell package instead, which rexports this plugin together with necessary specifications for definitions in the boot libraries.

Michael and Scott lock-free queues. Michael and Scott queues are described in their PODC 1996 paper: http://dl.acm.org/citation.cfm?id=248052.248106 These are single-ended concurrent queues based on a singlly linked list and using atomic CAS instructions to swap the tail pointers. As a well-known efficient algorithm they became the basis for Java's ConcurrentLinkedQueue.
