SHEN RUBY — S42 / KLambda bootstrap port
========================================

Run
---
Double-click shen.bat.

No separate Ruby installation is required. On the first run, Shen silently
unpacks/installs the bundled Ruby 4.0.7-1 x64 runtime into this folder's
runtime\ directory. It does not rely on Ruby being on PATH.

After that, shen.bat directly runs:

    runtime\bin\ruby.exe

The included Ruby installer is the file supplied with this package and is
used only to create the local runtime directory.

Test
----
Double-click test-shen.bat.

Updating Shen
-------------
Replace the KLambda directory with a newer compatible KLambda directory,
then run test-shen.bat.

Architecture
------------
Ruby implements the KLambda substrate and compiles loaded KLambda functions
to Ruby methods. Shen itself is loaded directly from KLambda. Ruby does not
implement Shen partial application/currying; that is handled by Shen.

The launcher reserves a larger Ruby VM stack for Shen programs with deep
non-tail recursion. No user configuration is required.
