The Bluetail Ticket Tracker (BTT) is a system for creating, storing, and keeping track of tickets. A ticket describes an issue of some sort. It can, for example, be a Trouble Report or a ToDo note. BTT also makes it possible to store customer information, which can be coupled to a ticket. BTT comes with a wiki-style knowledge base and an automatic mail store.
Esdl is library for accessing SDL and OpenGL through Erlang. SDL handles 2d graphics, user events, and audio while OpenGL handles 3d graphics. SDL (Simple DirectMedia Layer) is a cross-platform multimedia library designed to provide fast access to the graphics framebuffer and audio device. It also does event handling from mouse, keyboards, and joysticks. OpenGL is a cross-platform standard for 3D rendering and 3D hardware acceleration.
REPOS stands for Repository of Erlang-Projects.Org Software selection. It is a collection of major ready-to-use Erlang software. Erlang REPOS is distributed as a CDROM image (ISO). You can use every program included in the REPOS environment either directly from the CDROM, from your hard drive, or from a USB key.
J-EAI is an XMPP-based Enterprise Application Integration (EAI) platform (also known as ESB, the Enterprise Service Bus).

Serlvers is a set of Erlang modules designed to help in the implementation of IP services (i.e. TCP/IP or Internet servers). Serlvers consists of a set of behaviours to abstract the internals of each protocol, and other modules to help with the infrastructure. The goal is that when making a server, you only need worry about how to store, handle, process, etc. the information instead of the internals of each protocol (to save countless hours of RFC reading).
