| # This script is a thin wrapper around Cargo that provides human-friendly |
| # toolchain names which are automatically translated to the toolchain versions |
| # we have pinned in CI. |
| # |
| # cargo.sh --version <toolchain-name> # looks up the version for the named toolchain |
| # cargo.sh +<toolchain-name> [...] # runs cargo commands with the named toolchain |
| # cargo.sh +all [...] # runs cargo commands with each toolchain |
| # |
| # The meta-toolchain "all" instructs this script to run the provided command |
| # once for each toolchain (msrv, stable, nightly). |
| # |
| # A common task that is especially annoying to perform by hand is to update |
| # trybuild's stderr files. Using this script: |
