+# This program is used to verify the FS history code.
+#
+# The basic gist is this: given a repository, a path in that
+# repository, and a revision at which to begin plowing through history
+# (towards revision 1), verify that each history object returned by
+# the svn_fs_history_prev() interface -- indirectly via
+# svn_repos_history() -- represents a revision in which the node being
+# tracked actually changed, or where a parent directory of the node
+# was copied, according to the list of paths changed as reported by
+# svn_fs_paths_changed().
+#
+# A fun way to run this:
+#
+#   #!/bin/sh
+#
+#   export VERIFY=/path/to/verify-history.py
+#   export MYREPOS=/path/to/repos
+#
+#   # List the paths in HEAD of the repos (filtering out the directories)
+#   for VCFILE in `svn ls -R file://${MYREPOS} | grep -v '/$'`; do
+#     echo "Checking ${VCFILE}"
+#     ${VERIFY} ${MYREPOS} ${VCFILE}
+#   done
