## Deprecation shim — delegates to the cargo-dist-generated installer.

## DEPRECATED: will be removed after 2027-01-01.
## Use the new installer instead:
##
##   curl --proto '=https' --tlsv1.2 -LsSf \
##     https://github.com/pact-foundation/pact-cli/releases/latest/download/pact-installer.sh | sh
##
## To install a specific version:
##   curl --proto '=https' --tlsv1.2 -LsSf \
##     https://github.com/pact-foundation/pact-cli/releases/download/<VERSION>/pact-installer.sh | sh
