options for rdimport(1) in 'utils/rdimport/markerset.cpp',,
'utils/rdimport/markerset.h', 'utils/rdimport/rdimport.cpp' and
'utils/rdimport/rdimport.h'.

method.
* Added 'docs/metadata_wildcards.txt'.
* Implemented support for the '%i' ['Cut Description'] wildcard in
rdimport(1)'s '--metadata-pattern' switch in
'utils/rdimport/rdimport.cpp' [Github Issue #6].

rdimport(1)'s '--metadata-pattern' switch in
'utils/rdimport/rdimport.cpp'.
* Implemented support for the '%y' ['Release Year'] wildcard in
rdimport(1)'s '--metadata-pattern' switch in
