DESCRIPTION
       This package provides the frontend of a compiler of magic(5) files into
       recognizers  based  on the fileutil::magic::rt recognizer runtime pack-
       age. 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 directo-
              ries and compiles all the files, and the files in all the direc-
              tories 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  gener-
              ated 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 recognizer 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 creation, with  file/directory  "FOO"
              causing  the creation of procedure ::fileutil::magic::/FOO::run.
