# Bootstrap section.


# Bootstrapped modules must be special-cased, as they should be built prior to
# any parse-transform (here, the WOOPER one) using them, and the resulting BEAM
# must be produced in the right directory (not at the root).

# See also: in GNUmakevars.inc, the BOOTSTRAP_MODULES variable.


# We still need a special build here, so that the BEAM is generated in src
# rather than at the root of WOOPER:
