+/**
+   post-js-header.js is to be prepended to other code to create
+   post-js.js for use with Emscripten's --post-js flag. This code
+   requires that it be running in that context. The Emscripten
+   environment must have been set up already but it will not have
+   loaded its WASM when the code in this file is run. The function it
+   installs will be run after the WASM module is loaded, at which
+   point the sqlite3 WASM API bits will be set up.

+     - sqlite3-api-prologue.js  => Bootstrapping bits to attach the rest to
+     - sqlite3-api-whwasmutil.js  => Replacements for much of Emscripten's glue
+     - sqlite3-api-jaccwabyt.js => Jaccwabyt (C/JS struct binding)
+     - sqlite3-api-glue.js      => glues previous parts together

+     - sqlite3-api-worker.js    => Worker-based API
+     - sqlite3-api-cleanup.js   => final API cleanup
+     - post-js-footer.js        => closes this postRun() function
