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 consumption, 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 pack-age package
              age fileutil::magic::rt to perform its duties.
