# browser/Mmakefile - this is the Mmakefile for building the Mercury
# browser library, which also includes other functionality needed
# by Mercury debuggers.

# Since the code in this directory is intended to be invoked only from
# the trace library, which turns off tracing in the Mercury code it calls,
# compiling the modules in this directory with tracing on only makes
# the generated code much bigger. However, since all Mercury code
# in an executable must be of the same grade, we need to be able to
# compile the modules in this directory in debug grades as well.
