So, looking at the current files included in the installer:
https://github.com/bitkeeper-scm/bitkeeper/blob/master/src/import.sh#L952
https://github.com/bitkeeper-scm/bitkeeper/blob/master/src/import.sh#L834
https://github.com/bitkeeper-scm/bitkeeper/blob/master/src/import.sh#L709

from a quick check, this seems to be run with "bk import".

There is this file
https://github.com/bitkeeper-scm/bitkeeper/blob/master/src/bk.sh#L283
https://github.com/bitkeeper-scm/bitkeeper/blob/master/src/bk.sh#L337
nder the name bk.script

And apply-patch:
https://github.com/bitkeeper-scm/bitkeeper/blob/master/src/applypatch.sh#L33

And that' just on the shell code.

There is also fun stuff like
https://github.com/bitkeeper-scm/bitkeeper/blob/master/src/gnu/diffutils/sdiff.c

whose last edit is in 2000, but in 2001, someone found CVE-2001-0117
