PCL is a software library to access hardware performance counters on many microprocessors through a uniform interface and with low overhead. Language bindings exist for C, C++, Fortran, and Java. It is intended to be used by the expert application programmer who wishes to do detailed analysis on program performance, and it is intended to be used by tool writers which need a common platform to base their work on.
winestart is a program that is useful for collecting information on programs that run under Wine while they are being executed. It serves the purpose of writing logging information to disk (and optionally to stdout at the same time) in order to reproduce errors that appear at runtime. It also provides a simple way of switching between several installed Wine versions.
Barter is a tool for increasing the quality of applications written in Java. It allows the programmer to use design by contract and define other development aspects right in the classes and interfaces where they are relevant, as JavaDoc comments. It is essentially a code generator for AspectJ, implemented as an xDoclet task.
snip is an Ant task designed to help with the single-sourcing of program documentation. This task extracts snippets of text from files, placing them into properties in the Ant project. These properties can then be used by any other Ant task, and are particularly useful when referenced by <filter>s within the <copy> task. It was originally written to keep snippets of sample code in API documentation synchronized with the actual sample classes by automatically extracting code from the samples when the project is built.
Rundoc is an Ant task designed to help with the single- sourcing of program documentation. This task replaces special commands embedded within text files with their output in a specified format. Currently, only Docbook format is supported. It was written to keep sample code output in program documentation synchronized with the actual output of the current code, by running the referenced code when the documentation is built.
x4juli is a port of the main parts of log4j to the J2SE Logging API. The default implementation is incomplete and therefore still not widely used, even when introduced in J2SE 1.4. x4juli provides logmanagers, formatters, handlers, and filters to fill the gap. The interface and use of the original API has not been changed. Additionally, x4juli delivers a native implementation of the Jakarta Commons Logging (JCL) API and the Simple Logging Facade for Java (SLF4J) API.
Macker is an architectural rule-checking utility for Java. It's meant to model the architectural ideals programmers always dream up for their projects, and then break. It is not a lint checker--it operates on a more global, more logical level, focusing on class dependencies rather than source code formatting. Macker has no default set of rules; it's flexible, and writing a rules file is part of the development process for each unique project. You can tailor a rules file to suit a specific project's structure, or write some general "good practice" rules for your code. Macker typically runs as an Ant task, but can also be invoked with a shell script.
