doubt in quote-like operators

[anand kumar]

hi all,
   
  I could not understand clearly the functions 
qw(),qq(),qr(),qx(),q(),quotemeta(). I 
  have read the explanation for these functions in the perl documentation but i 
  could not get idea of where exactly we can use these functions. So please 
  send some other links or examples for these functions.
   
  Thanks in advance for the help
   
  Regards
  Anand Kumar
