public class RenameAttribute
extends SimpleStreamFilter

This filter is used for renaming attribute names.
Regular expressions can be used in the matching and replacing.
See Javadoc of java.util.regex.Pattern class for more information:
http://java.sun.com/javase/6/docs/api/java/util/regex/Pattern.html

Valid options are:

 -find <regexp>
  The regular expression that the attribute names must match.
  (default: ([\s\S]+))

 -replace <string>
  The string to replace the regular expression of matching attributes with.
  Cannot be used in conjunction with '-remove'.
  (default: $0)

 -remove
  In case the matching string needs to be removed instead of replaced.
  Cannot be used in conjunction with '-replace <string>'.
  (default: off)

 -all
  Replaces all occurrences instead of just the first.
  (default: only first occurrence)

 -R <range>
  The attribute range to work on.
 This is a comma separated list of attribute indices, with "first" and "last" valid values.
  Specify an inclusive range with "-".
  E.g: "first-3,5,6-10,last".
  (default: first-last)

 -V
  Inverts the attribute selection range.
  (default: off)
