__________________________________________________________________________________________________________________________________________________

NAME

       fileutil::magic::mimetype - Procedures implementing mime-type recognition

SYNOPSIS

       package require Tcl  8.4

       package require fileutil::magic::mimetype  ?1.0.2?

       ::fileutil::magic::mimetype filename

_________________________________________________________________

DESCRIPTION

       This package provides a command for the recognition of file types in pure Tcl. The output is standardized to mime-types.

       The  core  part	of the recognizer was generated from a "magic(5)" file containing the checks to perform to recognize files, and associated
       mime-types.

       ::fileutil::magic::mimetype filename
	      This command is similar to the command fileutil::fileType.

	      The output of the command for the specified file is not a list of attributes describing the type of the file, but a list of standard
	      mime-types the file may have.

	      This list will be empty if the type of the file is not recognized.

REFERENCES

       [1]    File(1)  sources	[ftp://ftp.astron.com/pub/file/]  This site contains the current sources for the file command, including the magic
	      definitions used by it. The latter were used by us to generate this recognizer.
