# This test puts MakeMaker through the paces of a basic perl module
# build, test and installation of the Big::Fat::Dummy module.
# Module::Install relies on being able to patch the generated Makefile
# to add flags to $(PERL)
# This test includes adding ' -Iinc' to $(PERL), and checking 'make install'
# after that works. Done here as back-compat is considered basic.
