The Jakarta-ORO Java classes are a set of text-processing Java classes that provide Perl5 compatible regular expressions, AWK-like regular expressions, glob expressions, and utility classes for performing substitutions, splits, filtering filenames, etc. This library is the successor to the OROMatcher, AwkTools, PerlTools, and TextTools libraries from ORO, Inc. (www.oroinc.com). They have been donated to the Jakarta Project by Daniel Savarese (www.savarese.org), the copyright holder of the ORO libraries. Daniel will continue to participate in their development under the Jakarta Project.
