K-tree provides a scalable approach to clustering by combining the B+-tree and k-means algorithms. Clustering can be used to solve problems in signal processing, machine learning, and other contexts. It has recently been used at INEX 2008 to solve document clustering problems on the Wikipedia corpus.

fileutil::magic::cgen - Generator core for compiler of magic(5) files
SYNOPSIS
package require Tcl 8.4
package require fileutil::magic::cgen ?1.0?
package require fileutil::magic::rt ?1.0?
package require struct::tree
package require struct::list
::fileutil::magic::cgen::2tree script
::fileutil::magic::cgen::treedump tree
::fileutil::magic::cgen::treegen tree node
_________________________________________________________________DESCRIPTION
This package provides the generator backend for a compiler of magic(5) files into recognizers based on the fileutil::magic::rt recognizer
runtime package. For the compiler frontend using this generator see the package fileutil::magic::cfront.
COMMANDS
::fileutil::magic::cgen::2tree script
This command converts the recognizer specified by the script into a tree and returns the object command of that tree as its result.
It uses the package struct::tree for the tree.
The script is in the format specified by magic(5).
::fileutil::magic::cgen::treedump tree
This command takes a tree as generated by ::fileutil::magic::cgen::2tree and returns a string encoding the tree for human consump-
tion, to aid in debugging.
::fileutil::magic::cgen::treegen tree node
This command takes a tree as generated by ::fileutil::magic::cgen::2tree and returns a Tcl script, the recognizer for the file types
represented by the sub-tree rooted at the node. The generated script makes extensive use of the commands provided by the recognizer
runtime package fileutil::magic::rt to perform its duties.
