-# official Conan Center Index is updated.
-conan remote add --force --index 0 xrplf https://conan.ripplex.io

-# lockfile.
-conan remove '*' --confirm

-# Create a new lockfile that is compatible with Linux, macOS, and Windows. The
-# first create command will create a new lockfile, while the subsequent create
-# commands will merge any additional dependencies into the created lockfile.
