zzuf is a transparent application input fuzzer. Its purpose is to find bugs in applications by corrupting their user-contributed data, which frequently comes from untrusted sources on the Internet. It works by intercepting file and network operations and changing random bits in the program's input. zzuf's behavior is deterministic, making it easier to reproduce bugs.
Flex Bison C++ Template is a code template that can be used to integrate a Flex scanner and Bison parser pair into a modern C++ program. These two universal tools are very difficult to incorporate into a good C++ design. The template utilizes both Flex and Bison in C++ mode and their output are encapsulated into classes. Thus the lexer and parser become fully reentrant, and multiple distinct lexer-parser pairs can easily be linked into one binary. The code implements a simple infix-notation calculator as an example, which can be used as a starting-point for you to insert your grammar.
QuHelp is a command-line program that scans a directory with HTML formatted text files and builds a help site using that directory's content and a template. A default template is included, but any template can be specified. QuHelp adds a nice expandable tree view of the help site's contents, a navigator, permalinks, and other useful stuff for browsing the help site.
