#!/usr/bin/make
#^^^^ help emacs select makefile mode
#
# This is a sub-make for building a standalone kvvfs-based
# sqlite3.wasm. It is intended to be "include"d from the main
# GNUMakefile.
#
# Notable potential TODOs:
#
# - Trim down a custom sqlite3-api.js for this build. We can elimate
# the jaccwabyt dependency, for example, because this build won't
# make use of the VFS bits. Similarly, we can eliminate or replace
# parts of the OO1 API, or provide a related API which manages
# singletons of the localStorage/sessionStorage instances.
