-#   Usage:
-#
-#   centos-art shell --update-topcomment=path/to/dir --filter=filename
-#
-# In the above usage example `path/to/dir' represents the parent
-# directory where shell scripts, you want to update top comment, are.
-# The `--filter=filename' argument is optional and if provided just
-# the file specificed is affected. Otherwise all files ending in `.sh'
-# are massively modified.
