<div class="paragraph"><p>A comment of the form <span class="monospaced">(*#showBasis "&lt;file&gt;"*)</span> is recognized as a directive to
save the current basis (i.e., environment) to <span class="monospaced">&lt;file&gt;</span> (in the same format as
the <span class="monospaced">-show-basis &lt;file&gt;</span> <a href="CompileTimeOptions"> compile-time option</a>).  The
<span class="monospaced">&lt;file&gt;</span> is interpreted relative to the source file in which it appears.  The
comment is lexed as a distinct token and is parsed as a structure-level
declaration.  [Note that treating the directive as a top-level declaration would
prohibit using it inside a functor body, which would make the feature
significantly less useful in the context of the MLton compiler sources (with its
nearly fully functorial style).]</p></div>
<div class="paragraph"><p>This feature is meant to facilitate auto-completion via
<a href="https://github.com/MatthewFluet/company-mlton"><span class="monospaced">company-mlton</span></a> and similar
tools.</p></div>
