#
# It clones (or updates) the repo, then runs bootstrap.ps1 to steer you into a
# Unix environment (WSL recommended). Override the defaults with env vars:
#   $env:QBJS_DIR = 'C:\path\to\dir'   where to clone   (default: ~\qbjs-docker)
#   $env:QBJS_REF = 'branch-or-tag'    what to check out (default: main)
#
# Note: this runs inside your current PowerShell session (that's how `iex` works),
# so it uses `return` (never `exit`) for early-outs, and launches bootstrap.ps1 in
# a child process -- otherwise their `exit` would close your window.
