+Usage:
+
+ persist-ephemeral-txnprops.py REPOS_PATH TXN_NAME [PREFIX]
+
+Duplicate ephemeral transaction properties so that the information
+they carry may persist as properties of the revision created once the
+transaction is committed. This is intended to be used as a Subversion
+pre-commit hook script.
+
+REPOS_PATH is the on-disk path of the repository whose transaction
+properties are being examined/modified. TXN_NAME is the name of the
+transaction.
+
+By default, ephemeral transaction properties will be copied to new
+properties whose names lack the "svn:" prefix. "svn:txn-user-agent"
+will, then, persist as "txn-user-agent". If, however, the optional
+PREFIX string argument is provided, it will be prepended to the base
+property name in place of the "svn:" namespace. For example, a prefix
+of "acme" will cause the "svn:txn-user-agent" property to be copied
+to "acme:txn-user-agent".
