Rename Finder Items by Pattern 0.1
Automator action for renaming the Finder items passed to it using a wildcard pattern
Rename Finder Items by Pattern works in similar fashion to the built in Rename Finder Items Automator action, but it uses a substitution pattern and a wildcard pattern to selectively pick parts of the current file name to use in the new file name.
In the replacement pattern, use a '$' and a number to substitute each wildcard match sequentionally (e.g. "foo-*-*" has two wildcards that can be used in the replacement pattern as "$1.bar.$2").
