The Linux From Scratch project is intended for Linux users who want to build their own custom Linux system. Reasons for wanting to build such a system are diverse. Perhaps you want to get into more detail as to what happens behind the scenes. Perhaps you are fed up with the bloated standard distributions. Or perhaps you don't want to rely on pre-compiled binaries out of concerns for security.
Syslinux is a collection of boot loaders for Linux and other operating systems which operates on Linux ext2/ext3 filesystems, MS-DOS FAT filesystems, network servers using PXE firmware, or from CD-ROMs. Syslinux has an advanced extension API and contains two optional menu systems. It also includes MEMDISK, a tool for booting legacy operating systems from non-traditional media like PXE or CD-ROM.
xplain2sql converts files from Xplain to SQL. It supports a very large subset of Xplain, and it can convert from Xplain to Microsoft SQL Server, DB/2, Inprise InterBase, PostgreSQL, Oracle, MySQL 5, SQLite 3 or ANSI-92 SQL. It can also generate an XML description of the generated SQL. This XML description can be used to create low-level middle-tier code. Example stylesheets for Eiffel/ECLI and Delphi/ADO are included. The C source code release should compile on any platform with an ANSI C compiler. There are binary releases for FreeBSD, Linux, Solaris x86, and Windows 2000.
CreEPS is a collection of C++ classes that provide an easy-to-use interface for generating vector plots from within code. The drawings are stored as Encapsulated Postscript (EPS) files. It features all basic drawing elements, user-configurable fill types, and printf-style text output. Extensive documentation with many examples is included.
Thread Safe Template Library (TSTL) is a C++ library that provides thread-safe containers with high grade of locking. It includes classes for multimaps based on a B-tree and a hash table. It also includes classes for a queue, a priority queue, a pipe, an alloccache, a timercache, a limitcache without global locking, and a fast shared mutual exclusion locker (also known as "rwlock" or "wmrg"). It's useful for writing multi-threaded applications, network services, and operating system components with high requirements for interactivity level.
runawk is a small wrapper for the AWK interpreter that helps one write standalone AWK scripts. Its main feature is to provide a module/library system for AWK which is somewhat similar to Perl's "use" command. It also allows one to select a preferred AWK interpreter and to set up the environment for AWK scripts. Dozens of ready for use [modules].awk are also provided.
The Parsing Expression Grammar Template Library (PEGTL) is a C++0x library for creating parsers according to a Parsing Expression Grammar (PEG). Grammars are embedded as regular C++ code, created with template programming (not template meta programming). These hierarchies naturally correspond to the inductive definition of PEGs. The library extends on the subject of PEGs with new expression types, actions that can be attached to grammar rules, and mechanisms to ensure helpful diagnostics in case of parsing errors. PEGs are superficially similar to Context-Free Grammars (CFGs).
delegate.c implements an abstract function pointer by capturing a user-specified callback signature -- delegate() -- and exposing it through a simple interface -- invoke(). It provides something loosely approximating lambda expressions; or even more analogous, C# delegates. It includes a wrapper to support libevent callbacks to functions not matching the required libevent callback signature.
modu is a high-level toolkit for building database-driven Web applications in Python. It provides all the common components needed to build custom Web applications in Python, including form generation, object-relational database mapping support, pluggable template systems, database-resident session and user support, and more.
