def copy(source, dest = 0, replace = FILE_EXISTS_RENAME):
  """
   Copies a file to a new location.
   This is a powerful function that in many ways
   performs like an advanced version of copy().
   - Checks if source and dest are valid and readable/writable.
   - Performs a file copy if source is not equal to dest.
   - If file already exists in dest either the call will
     error out, replace the
     file or rename the file based on the replace parameter.
  
   @param source A string specifying the file location of the original file.
     This parameter will contain the resulting destination filename in case of
     success.
   @param dest A string containing the directory source should be copied to.
     If this value is omitted, Drupal's 'files' directory will be used.
   @param replace Replace behavior when the destination file already exists.
     - FILE_EXISTS_REPLACE - Replace the existing file
     - FILE_EXISTS_RENAME - Append _{incrementing number} until
       the filename is unique
     - FILE_EXISTS_ERROR - Do nothing and return False.
   @return True for success, False for failure.
