| //! Run bootstrap from any subdirectory of a rust compiler checkout. |
| //! |
| //! We prefer `exec`, to avoid adding an extra process in the process tree. |
| //! However, since `exec` isn't available on Windows, we indirect through |
| //! `exec_or_status`, which will call `exec` on unix and `status` on Windows. |
| //! |
| //! We use `powershell.exe x.ps1` on Windows, and `sh -c x` on Unix, those are |
| //! the ones that call `x.py`. We use `sh -c` on Unix, because it is a standard. |
| //! We also don't use `pwsh` on Windows, because it is not installed by default; |
