#   sh.sh -- This module retrieves translatable strings from shell
#   scripts files. Normally, this function takes the file provided as
#   argument in the command-line and creates a list of all files that
#   share the same file extension in the same directory structure and
#   retrieve translation messages from it.  Translation messages are
#   stored in a PO file for each supported language under the Locales
#   directory. In case the --recursive option is also provided, the
#   list of files to process is build recursively.
