-      to the standard parameters calculated for that device.  This is used
-      to capture parameters which cannot easily be inferred from the layout.
-      For example, an RF device model might be distinguished from a non-RF
-      device model by a parameter such as <B>rfmode=1</B>.  Whether or not
-      a device is intended for RF use is not easily guessed from the layout,
-      and so "tagging" the gate with the parameter allows the correct model
-      parameters to be used for the device. <P>
-
-      A gate attribute that is not in the form of a parameter will be used
-      as the device's instance index in the netlist;  e.g.,  a label of
-      "<B>1^</B>" on a MOSFET gate extracted as a MOSFET device would be an
-      entry "<B>M1</B>" in the netlist.  This can be used to better track
-      device indexes between a schematic and layout. <P>
-
-      A label that is placed on the <I>edge</I> a device, specificlly  a
-      MOSFET gate, and which ends with the character "<B>$</B>", is a
-      <I>terminal attribute</I>.  The only terminal attributes recognized
-      by magic are <B>S$</B> and <B>D$</B>, which specify which side of the
-      gate is to be considered the source and which is to be considered the
-      drain.  Generally, MOSFET devices are symmetric, and their use in a
-      simulation does not depend on which side is in the position of the
-      "source" and which is in the position of the "drain".  To the extent
-      that it matters, the terminal attributes can be used to ensure that
-      the source and drain connections appear in the netlist in their
-      intended orientation. <P>
-
-      Labels ending with "<B>@</B>" are <I>node attributes</I>.  There is
-      currently no functional application for node attributes.  When one
-      is applied, it will appear in the output netlist in a SPICE comment
-      line indicating the node and attribute.  This could be used, say,
-      by a post-processing script, but as it is in a comment line, it has
-      no impact on simulation or LVS.

-# magic-vlsi-wasm
-
-[Magic VLSI](http://opencircuitdesign.com/magic/) layout tool, compiled to
-WebAssembly as a headless library. Runs in Node.js, browsers, and Web Workers
-— no X11, no Tk, no native dependencies.
-
-Use it to programmatically read and write `.mag`, `.gds`, `.cif`, `.ext`, and
-SPICE netlists; run DRC; extract parasitics — anywhere JavaScript runs.
-
-The package ships two variants:
-
-| Variant | Entry point | Description |
-|---------|-------------|-------------|
-| **notcl** (default) | `magic-vlsi-wasm` | Standalone — no Tcl interpreter. Commands are plain Magic command strings. |
-| **tcl** | `magic-vlsi-wasm/tcl` | Embeds a full Tcl 9 interpreter. Commands are evaluated as Tcl; Magic commands are available as the `::magic::` ensemble. |
-
-## Install
-
-The package is published to GitHub Packages. Add the following to your
-project's `.npmrc` so npm knows where to find it:
-
-```
-@rtimothyedwards:registry=https://npm.pkg.github.com
-```
-
-Then install:
-
-```bash
-npm install @rtimothyedwards/magic-vlsi-wasm
-```
-
-If the package is private or you hit a 401, authenticate with a GitHub
-[personal access token](https://github.com/settings/tokens) that has the
-`read:packages` scope:
-
-```
-//npm.pkg.github.com/:_authToken=YOUR_TOKEN
-@rtimothyedwards:registry=https://npm.pkg.github.com
-```
-
-Requires Node.js 18 or newer.
-
-## Quick start
-
-### Default variant (no Tcl)
-
-```js
-import createMagic from 'magic-vlsi-wasm';
-
-const { runCommand, FS } = await createMagic();
-
-// Drop a layout into Magic's virtual filesystem
-FS.mkdirTree('/work');
-FS.writeFile('/work/inv.mag', layoutBytes);
-
-// Run Magic commands — scmos is built into the WASM binary, no tech file needed
-runCommand('tech load scmos');
-runCommand('load /work/inv');
-runCommand('gds write /work/inv');
-
-// Read the result back out
-const gdsBytes = FS.readFile('/work/inv.gds');
-```
-
-### TCL variant
-
-```js
-import createMagic from 'magic-vlsi-wasm/tcl';
-
-const { runCommand, FS } = await createMagic();
-
-// Pure Tcl works directly
-runCommand('set x 42');
-runCommand('puts $tcl_version');
-
-// Magic commands are available as the ::magic:: ensemble
-runCommand('magic::tech load scmos');
-runCommand('magic::load /work/inv');
-runCommand('magic::gds write /work/inv');
-```
-
-The `scmos` technology family (`scmos`, `minimum`, `nmos`, ...) is embedded in
-the WASM binary and available out of the box — those names work without
-writing any tech file. To use a custom technology, write its `.tech` file into
-the VFS at `/magic/sys/current/<name>.tech` before calling `tech load <name>`.
-
-## API
-
-```ts
-createMagic(options?): Promise<MagicInstance>
-```
-
-`options` is forwarded to the underlying Emscripten module. Useful keys:
-
-| Key          | Default          | Purpose |
-|--------------|------------------|---------|
-| `wasmBinary` | fetched lazily   | Pre-fetched ArrayBuffer of `magic.wasm` (skips a network round-trip in browsers) |
-| `print`      | `console.log`    | Callback for each stdout line |
-| `printErr`   | `console.error`  | Callback for each stderr line |
-
-The returned `MagicInstance` exposes:
-
-| Method                    | Description |
-|---------------------------|-------------|
-| `runCommand(cmd: string)` | Dispatch a single Magic command. Returns 0 on success. |
-| `sourceFile(path: string)` | Execute a script from the virtual filesystem. Returns 0 on success, -1 if the file could not be opened. |
-| `init()`                  | Force initialization. Idempotent — `runCommand` and `sourceFile` call it for you. |
-| `update()`                | Drive a display-update cycle. No-op in this headless build. |
-| `FS`                      | Emscripten virtual filesystem. See the [Emscripten docs](https://emscripten.org/docs/api_reference/Filesystem-API.html). |
-
-Full TypeScript types ship in [`index.d.ts`](index.d.ts).
-
-### Low-level access
-
-`createMagic()` is a thin convenience wrapper over the underlying Emscripten
-module. If you need direct access — for example to call `cwrap` yourself or
-to drive `magic_wasm_init` manually — import the module factory directly:
-
-```js
-import createMagicModule from 'magic-vlsi-wasm/magic.js';
-
-const module = await createMagicModule({ wasmBinary, print, printErr });
-module._magic_wasm_init();
-const run = module.cwrap('magic_wasm_run_command', 'number', ['string']);
-run('tech load scmos');
-```
-
-The bundled examples use this lower-level path together with a small helper
-class ([`examples/helpers.js`](examples/helpers.js)) that adds a
-`runScript(text)` convenience method — it splits a multi-line Tcl block,
-strips comments, and dispatches each line via `runCommand`. Useful when you
-have a script as a string rather than as a file in the VFS.
-
-## Examples
-
-The package ships runnable examples for the most common workflows. After
-installing, run one directly:
-
-```bash
-node node_modules/magic-vlsi-wasm/examples/extract.js
-node node_modules/magic-vlsi-wasm/examples/gds.js
-node node_modules/magic-vlsi-wasm/examples/drc.js
-node node_modules/magic-vlsi-wasm/examples/cif.js
-```
-
-Or, when developing inside this repo:
-
-```bash
-npm test           # full suite (extract, gds, drc, cif)
-npm run example    # extract.js — RC extraction + SPICE netlist
-npm run test:gds   # GDS write only
-npm run test:drc   # DRC check only
-npm run test:cif   # CIF write only
-```
-
-Each example loads the bundled [`min.mag`](examples/min.mag) (a small NPN
-transistor cell from Magic's own scmos test suite) under the built-in `scmos`
-technology — no external tech file required. See [`examples/`](examples/) for
-the source; [`example.js`](examples/example.js) is the simplest entry point
-(GDS → CIF conversion in ~40 lines).
-
-## Build from source
-
-If you want to rebuild the WASM module yourself, see
-[`toolchains/emscripten/README.md`](../toolchains/emscripten/README.md).
-The short version:
-
-```bash
-bash npm/build.sh                    # both variants, debug build
-bash npm/build.sh --variant=notcl    # default variant only (faster)
-bash npm/build.sh --variant=tcl      # TCL variant only
-bash npm/build.sh --release          # optimized (-O2, no debug symbols)
-bash npm/build.sh --test             # build + run tests
-bash npm/build.sh --pack             # build + produce magic-vlsi-wasm-<version>.tgz
-```
-
-You will need an activated [emsdk](https://emscripten.org/docs/getting_started/downloads.html)
-on your PATH. If you pass `EMSDK_DIR=/path/to/emsdk`, `build.sh` sources
-`emsdk_env.sh` for you.
-
-### TCL variant: cloning the TCL source tree
-
-The TCL variant links against a static WASM build of
-[tcltk/tcl](https://github.com/tcltk/tcl). `build.sh` clones the source tree
-automatically into `build-tcl-wasm/tcl` on the first run and builds it
-out-of-source in the same directory — everything stays under `build-tcl-wasm/`
-(which is gitignored), so nothing outside it is touched. Subsequent runs reuse
-the existing clone and build.
-
-```bash
-# Override the TCL version or source repository
-TCL_REF=core-9-0-3 bash npm/build.sh --variant=tcl
-TCL_REPO_URL=https://github.com/tcltk/tcl.git bash npm/build.sh --variant=tcl
-```
-
-CI always resolves the latest stable `core-9-0-x` tag automatically. To build
-against a specific version, set `TCL_REF` in the environment.
-
-## Versioning
-
-Published versions follow the scheme `{MAJOR}.{MINOR}.{PATCH}0{YYYYMMDD}+git{SHA}`,
-for example `8.3.799020261231+git01234cde`.
-
-The date is embedded directly into the patch number (separated by a leading
-zero for readability). This means:
-
-- Versions are orderable numerically — a later build date is always a higher
-  version number within the same patch series.
-- Security or bugfix releases for `8.3.799` can be inserted as later dates
-  (`8.3.799020270101`, `8.3.799020270201`, …) without bumping the patch number.
-- Users who want to lock to the `8.3.799` series and receive only those patches
-  can use the range `<=8.3.799900000000` or `<8.3.8000000000000`.
-- `~8.3.799` matches all `8.3.*` versions (broader than the 799 series alone).
-
-The `+git…` suffix is build metadata — it is ignored by npm for version
-comparison and range matching. It exists purely for traceability.
-
-## Limitations
-
-- Headless only. There is no display driver, so commands that draw to a
-  window (`view`, `findbox`, interactive macros) are no-ops.
-- Single-threaded. WASM modules are not thread-safe — create one instance
-  per worker.

-### Bundled test layout
-
-The example layout [`examples/min.mag`](examples/min.mag) is taken from
-Magic's own scmos test suite ([`scmos/examples/bipolar/min.mag`](../scmos/examples/bipolar/min.mag))
-and is included here as a runnable smoke test for the WASM build. The `scmos`
-technology it targets is compiled into the WASM binary, so no external tech
-file is shipped.

-#   emcc / emmake / emconfigure  — Emscripten compiler tools
-#   make, gcc                    — standard build tools
-#   node, npm                    — only required for --test / --pack

-#   EMSDK_DIR     Path to an activated emsdk checkout.
-#                 If set, emsdk_env.sh is sourced from there.
-#                 If unset, emcc must already be on PATH (e.g. sourced externally).
-#   TCL_REF       git ref (tag/branch/SHA) of tcltk/tcl to build for the TCL
-#                 variant. Default: main. (CI pins the latest stable tag.)
-#   TCL_REPO_URL  git URL to clone tcltk/tcl from. Default: the upstream repo.
