#

#       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/.
