An extremely memory-efficient hash_map implementation. 2 bits/entry overhead! The Google SparseHash project contains several hash-map implementations in use at Google, with different performance characteristics, including an implementation that optimizes for space and one that optimizes for speed.

Python bindings for the D-BUS interprocess messaging system.

py-gearman is a pure Python Gearman library.

py-SymbolType is a Simple "symbol" type, useful for enumerations or sentinels.

Anyjson loads whichever is the fastest JSON module installed and provides a uniform API regardless of which JSON implementation is used.

PyBison is a Python binding to the Bison (yacc) and Flex (lex) parser-generator utilities. It allows parsers to be quickly and easily developed as Python class declarations, and for these parsers to take advantage of the fast and powerful C-based Bison/Flex. Users write a subclass of a basic Parser object, containing a set of methods and attributes specifying the grammar and lexical analysis rules, and taking callbacks for providing parser input, and receiving parser target events. Features * Runs at near the speed of C-based parsers, due to direct hooks into bison-generated C code * Full LALR(1) grammar support * Includes a utility to convert your legacy grammar (.y) and scanner (.l) scripts into python modules compatible with PyBison * Easy to understand - the walkthrough and the examples will have you writing your own parsers in minutes * Comfortable and intuitive callback mechanisms * Can export parse tree to XML with a simple method call * Can reconstitute a parse tree from XML

Java-Readline is a port of GNU Readline for Java. Or, to be more precise, it is a JNI-wrapper to Readline. It is distributed under the LGPL. You must call Readline.load(ReadlineLibrary lib); before using any other methods. If you omit the call to the load()-method, the pure Java fallback solution is used. Possible values for lib are: ReadlineLibrary.PureJava ReadlineLibrary.GnuReadline ReadlineLibrary.Editline ReadlineLibrary.Getline Note that all programs using GnuReadline will fall under the GPL, since Gnu-Readline is GPL software!

Lock file is a traditional means of synchronization among processes. In this module it is implemented as an empty regular file exclusively locked using fcntl.lockf. When it is to be released it is removed by default. However, if all cooperating processes turn off the removal, they get a guaranteed order of acquisitions and better scalability.

libcutl is a C++ utility library. It contains a collection of generic and independent components such as meta-programming tests, smart pointers, containers, compiler building blocks, etc.

libdasm is a C-library that tries to provide simple and convenient way to disassemble Intel x86 raw opcode bytes (machine code). It can parse and print out opcodes in AT&T and Intel syntax.
