Hi, This new code is slow (100x-150x) but does a good job finding dependencies which old code was useless. Here is the record:
$ time build-rdeps libopencc-dev Reverse Build-depends in contrib: --------------------------------- No reverse build-depends found for libopencc-dev. Reverse Build-depends in main: ------------------------------ ibus-libzhuyin ibus-pinyin libpyzy librime Found a total of 4 reverse build-depend(s) for libopencc-dev.
