Script for keeping main branches of external repos in sync with upstream

scripts/externalTests/update_external_repos.sh

+#!/usr/bin/env bash
+
+#------------------------------------------------------------------------------
+# Clones external test repositories from solidity-external-tests organization
+# and for each of them pulls latest upstream changes from the main branch and
+# pushes them to our fork.
+#
+# The script assumes that the current user has write access to
+# solidity-external-tests and that git is configured to be able to push there
+# without specifying the password (e.g. with the key already unlocked and loaded
+# into ssh-agent). Otherwise git will keep asking for password for each repository.
+#
+# Usage:
+#
+#    ./update_external_repos.sh [<target_dir>]
+#
+# <target_dir>: directory where the clones of the repositories are stored.
+#               If omitted, a temporary directory will be created.
