"""A simple bisector to bisect a list of arbitrary strings.
The strings to bisect are read from stdin, one item at a line.
Example:
Let's play the number guessing game. You choice a number in your mind
in range 1..99. You can lie within 20% probability. Let bisect-kit
guess.
Assume numbers less than your answer are considered as "old" and greater or
equals to your answer are "new".
$ seq 1 99 | ./bisect_list.py init --old 1 --new 99 --noisy=old=1/5,new=4/5
$ ./bisect_list.py config switch /bin/true
$ ./bisect_list.py config eval ./eval-manually.sh
$ ./bisect_list.py run
If you don't lie, just omit --noisy argument.
p.s. seq(1) prints a sequence of numbers, one at a line.
