EiffelStudio is an Integrated Development Environment (IDE) that provides comprehensive facilities to programmers. It offers a comprehensive suite of tools that enable programmers to produce correct, reliable, and maintainable software while keeping control of the development process. If you want to create fast, robust, scalable applications, then EiffelStudio™ will offer you a cost-effective solution. Imagine being able to model your system as you think – capturing your requirements and your thought processes with EiffelStudio. When ready to design, you build upon the model you just created, still with EiffelStudio. Then you implement with EiffelStudio. You never need to throw anything out and start over. You don’t need extra tools to go back and safely make changes in your architecture. Roundtrip engineering? It’s built in by design. Testing, metrics and productivity tools? They’re built in. EiffelStudio accommodates quickly and efficiently new thoughts and changes.

Simple and clean Framework core for your applications. Writen on pure PHP5.

My purpose is to create relatively small but functional library, that implements commonly used data structures like smart pointers, arrays and matrices. These classes should (if it's possible) look like 'normal' pointers or arrays but also should realize simple memory managemnets with reference counting and some additional functionality. I'm going to create lite-weight and handy interface for some scientific and engineering calculations instead of some monsters like MATLAB or etc. I'm not pretending for create something enormous and mega cool, but I'm trying to create lib for my special tasks. So, if you are interested then welcome to evaluate it and add your remarks. P.s. Sorry for my English, if something wrong.
