Reuse of existing solutions is typical for engineering and software engineering is not exception.
Increasing effectiveness of software products creation and support is an ultimate goal. Nowadays software
reuse is common approach for reaching this goal, so almost all modern methodologies and technologies
are concentrated on this problem. In this paper is proposed one more effective cross-project reuse technology
for artifacts described as text files collections (source code, XML, templates, HTML/CSS, etc); key idea
of this technology is storing similar software projects in generalization tree.
