Matreshka is a set of libraries to develop information systems. Or rather in this early stage of development, it is one library: League, which provides support for localization, internationalization and globalization.
It includes:
- Handling of string in unbounded form using Unicode representation and algorithms.
- Regular expression engine. It uses Perl-style syntax with Unicode extensions.
- XML document parser with SAX-style API.
