The Meta-Environment is

a framework for language development, source code analysis and source code transformation consisting of:

Syntax analysis tools.
Semantic analysis and transformation tools.
An interactive development environment.

The Meta-Environment is an open framework that

can be easily extended with third-party components;
can be easily tailored, modified, or extended;
is supported by an open source community.

The Meta-Environment is a generalization of the ASF+SDF Meta-Environment that has been successfully used in a wide variety of analysis, transformation and renovation projects.

Usage scenarios

The Meta-Environment can be used for many different purposes, including:

Parsing (new and old) programming languages, for further processing the trees, (e.g. COBOL, C, Java, PL/I, SQL)
Analysis of source code (fact extraction, type analysis).
Transformation of source code.
Generation of source code.
Design and implementation of domain-specific languages.
Generation and rapid prototyping of IDE's (Integrated Development Environments) for programming languages and domain specific languages
Generation of documentation from source code.
Compilation of domain specific languages (DSL).
Formal description of the syntax and semantics of (programming) languages.

See our extensive online user Documentation.

Interfaces

To facilitate reuse of components of The Meta-Environment by other toolkits, they are available through a number of different interfaces:

As an Interactive Development Environment (Screenshots).
As a collection of command line tools (Documentation).
As a collection of C and Java libraries (ApiDocumentation).
As a collection of ToolBus tools.

Each component is released separately for inclusion in other products. See ApiDocumentation for a list of components.
