ADTPro transfers disks to and from Apple II and Apple /// computers and the modern world using any of these communications methods: serial/USB, UDP via the Uthernet or LANceGS Ethernet cards, or audio via the Apple's cassette ports.

BitRock InstallBuilder allows you to create easy-to-use multiplatform installers for Linux (x86/PPC/s390/x86_64/Itanium), Windows, Mac OS X, FreeBSD, OpenBSD, Solaris (x86/Sparc), IRIX, AIX, and HP-UX applications. The generated application installers have a native look-and-feel and no external dependencies, and can be run in GUI, text, and unattended modes. In addition to self-contained installers, the installation tool is also able to generate standalone RPM packages.
CLNoFault is a tool to protect your files or plain text. Using XOR encryption, it can quickly encrypt data using either a username and a password of your choice, or an external file that will serve as a key. Encrypted files can't be recovered in any way besides re-encrypting them with CLNoFault with the correct user/pass combination or keyfile. CLNoFault is the console-based interface for the NoFault library (like KNoFault for KDE), so it is useful in scripts.
