+git-subtree-check.sh
+====================
+
+Run this script from the root of the repository to verify that a subtree matches the contents of
+the commit it claims to have been updated to.
+
+To use, make sure that you have fetched the upstream repository branch in which the subtree is
+maintained:
+* for `src/secp256k1`: https://github.com/bitcoin/secp256k1.git (branch master)
+* for `src/leveldb`: https://github.com/bitcoin/leveldb.git (branch bitcoin-fork)
+* for `src/univalue`: https://github.com/bitcoin/univalue.git (branch master)
+
+Usage: `git-subtree-check.sh DIR COMMIT`
+
+`COMMIT` may be omitted, in which case `HEAD` is used.
