Cil is an easy-to-use command-line driven distributed issue tracker. Using Git as it's storage backend, the power of a distributed version control system can be harnessed to enhance and provide powerful features. Cil saves the issues, comments, and attachments locally in plain-text for ease of use and easy accessibility.
FusionForge is a collaborative development environment that gathers in one single place several tools useful for development teams: communication tools (forums, mailing-lists, news, etc.); development tools (bug/patch trackers, project management, source control systems, etc.); and community tools (file releases, software categorization, Web site hosting, etc.). It is the continuation of the free software version of GForge, based on the codebase that was maintained in parallel to the proprietary GForge AS version.
BugStat is a script that allows you to run regular (i.e. cron based) queries to get more or less detailed bug statistics. The generated statistics are based on a predefined Bugzilla search. It requires Bugzilla's XML interface and has been tested with Bugzilla version 2.22.2 only, but should work with any later release as well.
Carp::Clan is a module that reports errors from the perspective of the caller of a "clan" of modules, similar to "Carp.pm" itself. Instead of giving it a number of levels to skip on the calling stack, you give it a pattern to characterize the package names of the "clan" of modules which shall never be blamed for any error. These modules stick together like a "clan" and any error that occurs will be blamed on the "outsider" script or modules not belonging to this "clan".
Savane is a Web-based Free Software hosting system, originally based on SourceForge 2.0. It currently includes issue tracking, project and member management, mailing lists, and individual account maintenance. The issue tracking handles bugs, tasks, and support. The issue tracker's fields ware configurable in many ways: mandatory of not, shown to users according to their role in a group, and with transition management.
bz2gnats is responsible for getting bugs from the Bugzilla database and changing their format to a text format so that the bugs may be used in a GNATS database. It leaves room for changes such as adding or deleting fields and it allows the ability to include all or some fields from Bugzilla.
The Anthill Bug Manager is a tool that aids code development by keeping track of bugs in a medium-sized coding environment. It accomplishes this with a clean, simple, and fast interface that contains the essential features, but avoids the complexity associated with similar tools. It is written in Perl, requires an SQL database as a backend, and is Web server independent.
