reposurgeon is a tool for editing version control repository history. It enables risky operations that version control systems don't want to let you do, such as editing past comments and metadata and removing commits. It works with any version control system that can export and import git fast-import streams, including git, hg, bzr, CVS, and RCS. It can also read Subversion dump files directly and can thus be used to script production of very high-quality conversions from Subversion to any supported DVCS.
deheader analyzes C and C++ files to determine which header inclusions can be removed while still allowing them to compile. This may result in substantial improvements in compilation time, especially on large C++ projects. It also sometimes exposes dependencies and cohesions of which developers were unaware.
svni is a wrapper for "svn ci" that provides an interactive check-in tool for Subversion. It features syntax checking before checking in files, the ability to make a last-minute selection of files when entering a commit message, and a display of the differences that are about to be checked in.
Maniac is a tool designed to automate the comparison and the validation of multiple variants of a same program. This is achieved by compiling each variant in a distinct shared object and generating a loader program that will successively load and execute them. The loader also takes charge of initializing input data and checking output data against the reference variant.
CERTivity is a powerful multi-platform visual tool for creating, managing, and handling different key store types (such as JKS, JCEKS, PKCS12, the Bouncy Castle types BKS and UBER, and Windows Native), public, private and secret keys in different formats (PKCS, OpenSSL, RSA/DSA, etc.), certificates (version 1 and 3), and certificates chains. It allows you to import and export keys, key pairs and certificates, manage certificate extensions, extend the validity period for self-signed certificates, test certificates, obtain revocation status, convert from one key store type to another, and much more.
