Project.py - does not accept -b ?

[0xc0170]

Looks like a regression. It used to be allowed to use -b :

Currently:

python tools\project.py -m K22F -i iar -n MBED_10 -b
usage: project.py [-h] [-m MCU] [-i IDE] [-c] [-p PROGRAM] [-n PROGRAM]
                  [-b BUILD] [-L] [-S] [-E] [--source SOURCE_DIR] [-D MACROS]
project.py: error: argument -b: expected one argument

It looks like it will accept -b, but expects an argument.

#2225 was probably supposed to delete the type line, not the action='store_true' line.
