 ExtUtils::Command - utilities to replace common UNIX commands in
 Makefiles etc.

   perl -MExtUtils::Command -e cat files... > destination
   perl -MExtUtils::Command -e mv source... destination
   perl -MExtUtils::Command -e cp source... destination
   perl -MExtUtils::Command -e touch files...
   perl -MExtUtils::Command -e rm_f files...
   perl -MExtUtils::Command -e rm_rf directories...
   perl -MExtUtils::Command -e mkpath directories...
   perl -MExtUtils::Command -e eqtime source destination
   perl -MExtUtils::Command -e test_f file
   perl -MExtUtils::Command -e test_d directory
   perl -MExtUtils::Command -e chmod mode files...
   ...

 The module is used to replace common UNIX commands.  In all cases the
 functions work from @ARGV rather than taking arguments.  This makes them
 easier to deal with in Makefiles.  Call them like this:

   perl -MExtUtils::Command -e some_command some files to work on

 and _N_O_T like this:

   perl -MExtUtils::Command -e 'some_command qw(some files to work on)'

 For that use Shell::Command.

 Filenames with * and ? will be glob expanded.

FFUUNNCCTTIIOONNSS #

 cat
         cat file ...

     Concatenates all files mentioned on command line to STDOUT.

 eqtime
         eqtime source destination

     Sets modified time of destination to that of source.

 rm_rf
         rm_rf files or directories ...

     Removes files and directories - recursively (even if readonly)

 rm_f
         rm_f file ...

     Removes files (even if readonly)

 touch
         touch file ...

     Makes files exist, with current timestamp

 mv
         mv source_file destination_file
         mv source_file source_file destination_dir

     Moves source to destination.  Multiple sources are allowed if
     destination is an existing directory.

     Returns true if all moves succeeded, false otherwise.

 cp
         cp source_file destination_file
         cp source_file source_file destination_dir

     Copies sources to the destination.  Multiple sources are allowed if
     destination is an existing directory.

     Returns true if all copies succeeded, false otherwise.

 chmod
         chmod mode files ...

     Sets UNIX like permissions 'mode' on all the files.  e.g. 0666

 mkpath
         mkpath directory ...

     Creates directories, including any parent directories.

 test_f
         test_f file

     Tests if a file exists.  _E_x_i_t_s with 0 if it does, 1 if it does not
     (ie.  shell's idea of true and false).

 test_d
         test_d directory

     Tests if a directory exists.  _E_x_i_t_s with 0 if it does, 1 if it does
     not (ie. shell's idea of true and false).

 dos2unix
         dos2unix files or dirs ...

     Converts DOS and OS/2 linefeeds to Unix style recursively.
