ZFolder2Product takes the contents of a Zope folder and creates a custom Zope Product, which then re-creates the entire folder contents when installed. The advantage of using ZFolder2Product over a normal Zope exportation is that the folder contents are saved in external files usable within a version control system like CVS. After re-importing the files, you can edit them using the Zope Management Interface and export them back to the filesystem.
PrEd is a Java-based graphical utility to find and edit Java property files in JAR, WAR, and other kinds of ZIP archives. It is an appropriate tool for customizing Java applications which use XML and Property files for their configuration. It provides an interface to edit the property values of property files and to edit the values of XML text nodes and attributes. No knowledge of XML is needed to edit XML files. The program can update JAR and WAR files without having to extract them.
Conary is a distributed software management system for Linux distributions. It replaces traditional package management solutions (such as RPM and dpkg) with one designed to enable loose collaboration across the Internet. It enables sets of distributed and loosely connected repositories to define the components which are installed on a Linux system. Rather than having a full distribution come from a single vendor, it allows administrators and developers to branch a distribution, keeping the pieces which fit their environment while grabbing components from other repositories across the Internet.
