8 Conclusion
</SectionTitle>
    <Paragraph position="0"> We have presented the steps in compiling head-driven generation code for ALE grammar signatures, which can make use of ALE's efficient compilation of descriptions. We have also outlined a method for compiling feature-based decision trees which can be used to alleviate the lexicon indexing problem for generation, as well as the chart edge indexing problem for large-scale feature-based parsers.</Paragraph>
    <Paragraph position="1"> All of these techniques have been implemented and will be available beginning with version 3.0 of ALE, which will be released in Spring, 1997.</Paragraph>
    <Paragraph position="2"> By compiling both logical operations and, in a processing-specific fashion, higher-level control operations, ALE can be used for very efficient, large-scale feature-based grammar design.</Paragraph>
