       This package provides implementations of standard unix utilities.

       ::fileutil::cat filename
	      A  tcl  implementation of the UNIX cat command.  Returns the contents of the speci-
	      fied file. The first argument is the name of the file to read.

       ::fileutil::fileType filename
	      An implementation of the UNIX file command, which uses various heuristics to  guess
	      the  type  of a file.  Returns a list specifying as much type information as can be
	      determined about the file, from most general (eg, "binary" or "text") to most  spe-
	      cific  (eg,  "gif").  For example, the return value for a GIF file would be "binary
	      graphic gif".  The command will detect the following  types  of  files:  directory,
	      empty,  binary,  text,  script  (with  interpreter),  executable	elf, graphic gif,
	      graphic jpeg, html, xml (with doctype if available), message pgp, and link.

       ::fileutil::find ?basedir ?filtercmd??
	      An implementation of the unix command find. Adapted from the Tcler's Wiki. Takes at
	      most two arguments, the path to the directory to start searching from and a command
	      to use to evaluate interest in each file. The path defaults to ".", i.e.	the  cur-
	      rent  directory.	The  command  defaults	to the empty string, which means that all
	      files are of interest. The command takes care not to loose itself in infinite loops
	      upon  encountering  circular  link structures.  The result of the command is a list
	      containing the paths to the interesting files.

       ::fileutil::findByPattern basedir ?-regexp|-glob? ?--? patterns
	      This command is based upon the TclX command recursive_glob, except that it  doesn't
	      allow  recursion	over  more than one directory at a time. It uses ::fileutil::find
	      internally and is thus able to and does follow symbolic links, something	the  TclX
	      command does not do. First argument is the directory to start the search in, second
	      argument is a list of patterns. The command returns a list of all  files	reachable
	      through  basedir whose names match at least one of the patterns. The options before
	      the pattern-list determine the style of matching, either regexp or glob. glob-style
	      matching	is  the  default  if  no  options are given. Usage of the option -- stops
	      option processing. This allows the use of a leading '-' in the patterns.

       ::fileutil::foreachLine var filename cmd
	      The command reads the file filename and executes the script cmd for every  line  in
	      the  file.  During  the execution of the script the variable var is set to the con-
	      tents of the current line. The return value of this command is the  result  of  the
	      last invocation of the script cmd or the empty string if the file was empty.

       ::fileutil::grep pattern ?files?
	      Implementation  of  grep. Adapted from the Tcler's Wiki. The first argument defines
	      the pattern to search for. This is followed by a list of files to  search  through.
	      The  list  is  optional  and stdin will be used if it is missing. The result of the
	      procedures is a list containing the matches. Each match is a single element of  the
	      list  and contains filename, number and contents of the matching line, separated by
	      a colons.

       ::fileutil::stripN path n
	      Removes the first n elements from the specified path and returns the modified path.
	      If n is greater than the number of components in path an empty string is returned.

       ::fileutil::stripPwd path
	      If  the  path  is  inside of the directory returned by [pwd] it is made relative to
	      that directory. In other words, the current working directory is stripped from  the
	      path.  The possibly modified path is returned as the result of the command.

       ::fileutil::touch ?-a? ?-c? ?-m? ?-r ref_file? ?-t time? filename ?...?
	      Implementation  of  touch. Alter the atime and mtime of the specified files. If -c,
	      do not create files if they do not already exist. If -r, use the	atime  and  mtime
	      from  ref_file.  If  -t, use the integer clock value time. It is illegal to specify
	      both -r and -t. If -a, only change the atime. If -m, only change the mtime.
