<p>
    UseTheSource is an open-source software community bringing together the core implementation of the <a
        href="https://www.rascal-mpl.org">Rascal metaprogramming language</a>, reusable libraries and tools for
    metaprogramming, as well as applications (tools) for specific programming languages and modelling languages based on
    Rascal.</p>

<p>The technology provided by UseTheSource either reads or writes source code (or both), or fundamentally supports one
    of these tasks. You can make software analysis and transformation tools with Rascal, but also checkers and code
    generators for domain specific languages. We apply Rascal to master <i>software complexity</i>: either by analyzing
    existing (legacy) systems, or by analyzing application domains and generating evolvable and portable
    implementations. Please read more <a href="./about/">here</a>.</p>

<p>
    All UseTheSource software is integrated into the <a
        href="https://marketplace.visualstudio.com/items?itemName=UseTheSource.rascalmpl">Rascal Meta Programming VScode
        extension</a>, creating the one-stop-shop language workbench for forward DSL engineering and reverse PL
    engineering. The Rascal VScode extension is a <a
        href="https://www.rascal-mpl.org/docs/Packages/RascalLsp/API/util/LanguageServer/">rapid prototyping and
        language engineering environment for VScode extensions for your own DSLs based on the LSP</a>
