See Pckgr's app libraryA lightweight, winget-installable Rust bootstrapper for RosBE.
`winget install` adds the `rosbe` command. Run `rosbe install` to
download and verify the RosBE toolchain bundle, then `rosbe enable`
to add the active toolchain directories to PATH.

- LLVM-MinGW (Clang) 21.1.7 - llvm-mingw 20251202 (UCRT)
- MinGW-GCC 15.2.0 - crosstool-NG Canadian-cross (UCRT)

`rosbe update` refreshes the toolchain bundle. `rosbe remove` removes
the installed bundle and PATH entries.
Not an official ReactOS release. Intended for preview / early adoption.

Copy a command tailored to that specific architecture, type, and scope - useful when winget would otherwise pick a different default.
No known CVEs for RosBE.
Coverage is best-effort and depends on a winget package mapping to an NVD CPE entry. Absence here is not a guarantee of safety.
