#
#       smidump test for various output formats and conversions.
#
# FORMAT=xxx : 
#   Check `smidump -f xxx' output for all TESTMIBS read from the libsmi MIB
#   repository against nominal dumps/xxx/ files.
#
# FORMAT=xxx-yyy :
#   Check `smidump -f yyy' output for all TESTMIBS read from dumps/xxx/
#   against nominal dumps/yyy-xxx/ files.
#
# FORMAT=orig-yyy : 
#   Check `smidump -f yyy' output for all TESTMIBS read from the libsmi MIB
#   repository against the original files from the repository. This is done
#   by extracting unified characteristics of both files of each check
#   (see the filter shell function) and comparing the diff with the nominal
#   diff in dumps/orig-yyy/.
