+
+  This is a JS Worker file for the main sqlite3 api. It loads
+  sqlite3.js, initializes the module, and postMessage()'s a message
+  after the module is initialized:
+
+  {type: 'sqlite3-api', result: 'worker1-ready'}
+
+  This seemingly superfluous level of indirection is necessary when
+  loading sqlite3.js via a Worker. Instantiating a worker with new
+  Worker("sqlite.js") will not (cannot) call sqlite3InitModule() to
+  initialize the module due to a timing/order-of-operations conflict
+  (and that symbol is not exported in a way that a Worker loading it
+  that way can see it).  Thus JS code wanting to load the sqlite3
+  Worker-specific API needs to pass _this_ file (or equivalent) to the
+  Worker constructor and then listen for an event in the form shown
+  above in order to know when the module has completed initialization.
+
+  This file accepts a URL arguments to adjust how it loads sqlite3.js:
+
+  - `sqlite3.dir`, if set, treats the given directory name as the
+    directory from which `sqlite3.js` will be loaded.
