#^^^^ 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.
