Hi,

=:dir= specifies the directory for code execution, i.e. when you hit =C-c
C-c= what is the environment in which the code is run?

=:mkdirp= forces creation of the directory for tangle output, i.e. when you
=org-babel-tangle= where do you put the output source code?

They are quite separate concerns.

Regards,
Sean
