AccuRev is a fast, powerful, and easy-to-use Software Configuration Management (SCM) tool with integrated issue tracking based on "Streams" that more efficiently manages complex parallel and global development. Streams are a combination and superset of branches and labels that are first class objects instead of being file-by-file attributes. AccuRev records all merges and patches, so you never have to re-merge the same code. It supports file and directory renaming and merging, follows a client/server model, and is transaction-based. It includes an integrated graphical 3-way diff and merge tool. AccuRev provides an Open API (and SDK) to integrate with any third-party development tool (IBM/Rational ClearQuest, Serena TeamTrack, and more out of the box). It also integrates with Eclipse, the MS SCC API (MS Visual Studio), Sun Java Studio, any diff/merge tool with a command line interface, and more.
Ghostscript is a processor for PostScript and PDF files. It can rasterize these files to a wide variety of printers, devices for screen preview, and image file formats. Since applications tend to prepare pages for printing in a high-level format such as PostScript, most Unix users with low-level bitmap printers, such as inkjets, use GhostScript as part of the printing process. In addition, Ghostscript is capable of converting PostScript files, functionality comparable to Adobe Acrobat Distiller, but on the command line. In addition, Ghostscript is used for file import and viewing by a great many other applications, including xv, ImageMagick, gimp, and xdvi. Several GUI wrappers for viewing PostScript and PDF files exist, including GSview, ghostview, gv, ggv, and kghostview. This is far from a comprehensive list.
