/**
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 this
file installs will be run after the WASM module is loaded, at which
point the sqlite3 JS API bits will get set up.

depending on whether this file is built with emcc 3.1.x or
4.0.x. This function name is intentionally obnoxiously verbose to
ensure that we don't collide with current and future Emscripten
symbol names. */

- common/whwasmutil.js => Generic JS/WASM glue
- jaccwabyt/jaccwabyt.js => C struct-binding glue
- sqlite3-api-glue.js => glues previous parts together
- sqlite3-api-oo1.js => SQLite3 OO API #1
- sqlite3-api-worker1.js => Worker-based API
- sqlite3-vfs-helper.c-pp.js => Utilities for VFS impls
- sqlite3-vtab-helper.c-pp.js => Utilities for virtual table impls
- sqlite3-vfs-opfs.c-pp.js => OPFS VFS

- sqlite3-api-cleanup.js => final bootstrapping phase
- post-js-footer.js => this file's epilogue

extern-post-js.js.
