DESCRIPTION
       This  package  provides  the  frontend  of a compiler of magic(5) files into recognizers based on the
       fileutil::magic::rt recognizer runtime package. For the generator backed used by  this  compiler  see
       the package fileutil::magic::cgen.

COMMANDS
       ::fileutil::magic::cfront::compile path...
              This  command takes the paths of one or more files and directories and compiles all the files,
              and the files in all the directories into a single recognizer for all the file types specified
              in these files.

              All the files have to be in the format specified by magic(5).

              The result of the command is a Tcl script containing the generated recognizer.

       ::fileutil::magic::cfront::procdef procname path...
              This command behaves like ::fileutil::magic::cfront::compile with regard to the specified path
              arguments, then wraps the resulting recognizer script into a procedure  named  procname,  puts
              code setting up the namespace of procname in front, and returns the resulting script.

       ::fileutil::magic::cfront::install path...
              This  command uses ::fileutil::magic::cfront::procdef to compile each of the paths into a rec-ognizer recognizer
              ognizer procedure and installs the result in the current interpreter.

              The name of each new procedure is derived from the name of the file/directory used in its cre-ation, creation,
              ation,    with   file/directory   "FOO"   causing   the   creation   of   procedure   ::fileu-til::magic::/FOO::run. ::fileutil::magic::/FOO::run.
              til::magic::/FOO::run.
