LZHAM is a general purpose lossless data compression library that borrows many ideas from LZMA, but purposely makes several key tradeoffs that favor decompression speed over compression ratio. LZHAM's compression ratio is typically within .5% of LZMA, but decompresses 2-3 times faster. LZHAM's compressor is heavily threaded in a way that does not sacrifice compression ratio. The decompressor supports streaming and memory to memory decompression, and is designed to be particularly fast on embedded devices, handhelds, and game console platforms.
Easylzma is a C library and command line tools for LZMA compression and decompression. It uses Igor Pavlov's reference implementation and SDK. It is meant to be a tiny wrapper and portable build system around a subset of Igor Pavlov's LZMA compression and decompression implementation. The API is small and intended to be straightforward. The project aims to support multiple different prominent LZMA file formats and is focused on producing something that is easy to build and use everywhere.
fakedbfs is a suite of tools and a library for cataloguing files. Anything that is a file can be catalogued along with metadata. The metadata is then searchable through various querying facilities. It runs entirely in userland and was inspired by BFS, which doesn't do content indexing, only metadata.
Rant is a flexible build tool. The equivalent to a Makefile for make is the Rantfile, which is actually a valid Ruby script that is read in by the rant command. It currently features automated testing, packaging, and RDoc generation for Ruby applications and libraries, creation of gzipped tar and zip archives on all supported platforms without additional software, recognition of file changes based on MD5 checksums, dependency checking for C/C++ source files (makedepend is not required), and more. It can generate a script tailored to the needs of a specific project, which can be used instead of an Rant installation so that users aren't dependent on Rant.
php_db2util is a module that extends PHP with mass data movement functions. It supports connecting to a DB2 server, loading data from a client or server with a replace option or insert option, and exporting data from a table to a client. It also allows the runstats utility to be run to recreate indexes.
The Enhanced File Crypt/eXtended File Stealth System (EFC/XFSS) makes your uploaded files safe on the server so that no one can read them without knowing a few details to decipher the files. It generates different obfuscated names and encrypted files so no one will know what the original format or name was.
CFL (Compressed File Library) is meant for the save-files used by games, and other sorts of data files. Its features include pluggable class factories, easy CFL file creation at runtime, and the ability to have multiple separate CFL objects in memory at the same time. The package also includes a CFL testing tool to make it easier to port the library and to create additional plug-in compressors, preprocessors, and ciphers. It also includes a makecfl utility, which makes it easy to create ini files.
