+# This script updates the sha256 hash of bottled binary packages with .sha256
+# files created when binary packages are bottled. It searches files under the
+# current directory with the suffix sha256, replaces root_url's version number,
+# and rebuilds the sha256-hash entries with the current bottle entries.
+#
+# The name of sha256 hash files should be,
+# <Formula-name>-<version>.<macosname>.bottle.<rebuildnumber>.sha256
+#
+# Usage:
+# $ updatee_bottles.sh <Formula names> or <Formula files>
+# Examples:
+# $ ./update_bottle.sh omniorb-ssl-py313
+# $ ./update_bottle.sh omniorb-ssl-*.rb
