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
              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.
