This is a long over due bug…

The library should be removed from Debian, it has been deprecated a long
tima ago, even I took over that libary in 2012, upstream had already
deprecated the library and had prominetnly on the homeage to use Kyoto
Cabinet instead [1,2]. (And according to Wikipedia, this has been replaced
with Tkrzz…[3] )

As now the library is showing it's age (#1114412), I'm going to file
bugs to ask the remaining reverse dependencies to migrate off
tokyocabinet with the final goal to remove tokyocabinet from Debian....

This bug is to track the removal process.
