COCANWIKI is a full-featured Wiki and content management system. It has many unique features not found in any other Wikis including live preview when editing, advanced navigation (including the ability to follow links in both directions), PIM/calendar extensions, user permissions, customisable page layouts, virtual hosting (handling more than one Wiki per server), search, anti-spam, and email notifications.
libguestfs is a set of tools for accessing and modifying virtual machine (VM) disk images. You can use this for viewing and editing files inside guests, scripting changes to VMs, monitoring disk used/free statistics, P2V, V2V, performing partial backups, cloning VMs, and much more. libguestfs can access nearly any type of filesystem including: all known types of Linux filesystem (ext2/3/4, XFS, btrfs, etc.), any Windows filesystem (VFAT and NTFS), any Mac OS X and BSD filesystems, LVM2 volumes, MBR and GPT disk partitions, raw disks, qcow2, CD and DVD ISO images, SD cards, and dozens more. libguestfs doesn't need root permissions.
mod_caml is a set of Objective CAML (OCaml) bindings for the Apache API. It allows you to run CGI scripts written in OCaml directly inside the Apache Web server. However, it is much much more than just that. You can bind to any part of the Apache request cycle, read and modify internal Apache structures, share modules of code between handlers and scripts, or use the CGI library and templating system (allows separation of code and presentation).
Monolith is an application framework for Web applications. It provides basic widgets for labels, buttons, images, input fields, and so on. The programmer uses these to construct whole applications or reusable "super-widgets" which can be embedded in other applications, distributed, or even sold. Writing Monolith widgets and applications strongly resembles tools like Java/Swing, Windows MFC, Motif, GTK, Tcl/Tk, etc. There are comprehensive manual pages for every widget and method, and a set of example programs.
Net::FTPServer is a full-featured, secure, extensible, and highly configurable FTP server which can serve files from a standard file system or a relational database. It is written in Perl, which provides natural protection against buffer overflows. It has feature parity with popular C-based servers such as wu-ftpd. The server offers virtual hosts (IP-based and experimental IP-less). It is configurable in Perl, for both small Perl "hacks" in the configuration file all the way up to complete server "personalities". It supports the latest RFCs and Internet Drafts. Authentication may be done through /etc/passwd, PAM or an authentication plug-in. Resource limits are supported. The server may run standalone or from inetd. chroot() jails are supported along with sophisticated programmable access control rules. All aspects of server use and configuration are comprehensively documented in a manual running to some 50 pages.
Virt-df is a df implementation for virtual guests. The program is meant to be run on the host or dom0 to display disk space used and available on all partitions within all guests. There is no need to run any software or agent inside the guests. It is compatible with most Linux and Windows guests.
