+This project includes SQLite via the `better-sqlite3` package.
+
+Apparently it needs to be rebuilt for Electron -- a standard prebuild for Node.js won't work --
+even when it's accessed from the main and not the renderer process.
+
+To install the necessary tools I simply installed the latest version of Node.js
+from https://nodejs.org/en/download/current/
+with the "Windows build tools" option enabled.
+I already had MSVC 2019 and 2015 (Community Edition) installed.
+
+I thought I might need this plugin but apparently it works without:

+  "@timfish/forge-externals-plugin",

+    "externals": ["better-sqlite3"],
+    "includeDeps": true
