+# update-deps-to-path.sh goal is to replace git dependencies with path dependencies
+# in the target Cargo.toml file.
+#
+# The script will scan the source repos for packages and build a mapping of package name to path.
+# It will then process the target Cargo.toml file line by line and replace git dependencies with path dependencies.
+#
+# The script will output the new Cargo.toml file to stdout.
+#
+# The script will exit with a non-zero status if the target Cargo.toml file is not found.
+# Usage: ./scripts/update-deps-to-path.sh ./Cargo.toml ../polkadot-sdk-otf  > Cargo.toml.new
