Untar a file.

For JDK 1.1 "last modified time" field is set to current time instead of being carried from the archive file.

PatternSets are used to select files to extract from the archive. If no patternset is used, all files are extracted.

FileSet>s may be used to select archived files to perform unarchival upon.

File permissions will not be restored on extracted files.

The untar task recognizes the long pathname entries used by GNU tar.

Since:
  Ant 1.1
