rem  dsh-origin-thesis launcher
rem ----------------------------------------------------------------------------
rem  Why a .cmd launcher instead of pointing DSH straight at python.exe?
rem
rem  DSH evaluates `!!js` expressions in a sandbox where `__dirname`,
rem  `__filename` and `require` are NOT available (measured: `typeof __dirname`
rem  raises "ReferenceError: __dirname is not defined"). Only `process` is
rem  reliably present. That makes it impossible for the patch file to compute its
rem  own package directory in JavaScript.
rem
rem  `%~dp0` is a standard Windows batch expansion for "directory of this
rem  script", so this launcher locates itself with no JS involved. The patch only
rem  has to name this file, and the package can live anywhere.
rem
rem  Interpreter resolution order:
rem    1. DSH_THESIS_PYTHON                       (explicit override)
rem    2. conda env `origin` in the usual places  (auto-detect)
rem    3. `python` on PATH                        (last resort)
rem
rem  The interpreter must be able to `import originpro`
rem  (originpro ships wheels up to python 3.9 only).
