I also noticed the same tools at http://www.savarese.org/oro/downloads/
This is the old software on which jakarta-oro is based and is no

The PerlTools have text/regex/Perl5StreamInput, and Jakarta source does not.
Are there any other significant differences?

The expression:
new Perl5Util().match(/[[:alpha:]]/, a)
