Log Toolkit provides a set of logfile processing tools. Include are tools to convert from W3C (IIS) to ELF (Apache extended log format), to convert from Netscape/iPlanet to ELF, to strip corrupt logfile lines, to sort logfile lines by date (useful for combining logs from mirrored servers), and to filter lines by URI prefix or result code (useful for stripping out logs for a subsection of a website). The tools try to be fast and memory efficient, and are useful for large logfiles or small systems.
The mission of the Apache Portable Runtime (APR) project is to create and maintain software libraries that provide a predictable and consistent interface to underlying platform- specific implementations. The primary goal is to provide an API to which software developers may code and be assured of predictable if not identical behaviour regardless of the platform on which their software is built, relieving them of the need to code special-case conditions to work around or take advantage of platform-specific deficiencies or features.
