This package includes general classes required by org.apache.oro.text and related packages, but that can also be applied to
more general uses.
The Jakarta-ORO library contains packages for performing general text
processing in Java, with an aim to support, though not specifically
limited to, servlet development. The core package is
org.apache.oro.text.regex, which defines abstract interfaces for
manipulating regular expressions, as well as a set of Perl5 comptabile
regular expression classes. Developers will mostly be interested only
in that package.
