+<h3>Project Activity Monitor</h3>
+
+<p>
+ This page monitors project activity status of modules developed and maintained by the <a href="https://logging.apache.org/">Apache Logging Services</a>.<br/>
+ Users can leverage this information to have an idea about the maintenance status of certain projects.<br/>
+ Users depending on less maintained modules might consider stepping up for maintenance to avoid deprecation.<br/>
+</p>
+
+<p>
+ Remember, <strong>this is just data!</strong><br/>
+ How to interpret these figures depends on your use case and modules associated.
+</p>
+
+<h3>Legend</h3>
+
+<dl>
+ <dt>#Commits</dt>
+ <dd>
+ This column denotes the number of commits.<br/>
+ The bar is in log-scale.<br/>
+ Green-Black-Orange-Red coloring is performed using a commit count range of 50-30-20.
+ </dd>
+ <dt>#Authors</dt>
+ <dd>
+ This column denotes the number of <em>active</em> PMC members authoring the commits.<br/>
+ The value is analogous to <a href="https://en.wikipedia.org/wiki/Bus_factor">the bus factor</a>.<br/>
+ Note that individual contributors and inactive PMC members are discarded.

+ // https://github.com/kripken/emscripten/issues/5820

+ // The way to affect the loading of emcc compiled modules is to create a variable called `Module` and add
+ // properties to it, like `preRun`, `postRun`, etc
+ // We are using that to get notified when the WASM has finished loading.
+ // Only then will we return our promise
+
+ // If they passed in a moduleConfig object, use that
+ // Otherwise, initialize Module to the empty object

+ // When that runs, it's going to overwrite our own modularization export efforts in shell-post.js!
+ // The only way to tell emcc not to emit it is to pass the MODULARIZE=1 or MODULARIZE_INSTANCE=1 flags,
+ // but that carries with it additional unnecessary baggage/bugs we don't want either.
+ // So, we have three options:
+ // 1) We undefine `module`
+ // 2) We remember what `module['exports']` was at the beginning of this function and we restore it later

+ // That's a nice side effect since we're handling the modularization efforts ourselves
