r_print-%:
@echo ‘====================’
@echo ‘NAME: $*’
@echo ‘——————–’
@echo ‘VALUE: $($*)’
@echo ‘——————–’
@echo ‘RULE: $(value $*)’
@echo ‘——————–’
@echo ‘ORIGIN: $(origin $*)’
@echo ‘====================’

Actually, I think it further underscores my point — I'm not a domain expert in the build system produced by this system (h2xs plus MakeMaker), and yet I was able to figure out how to work with it very quickly thanks to the assist from emake.

Makefiles are actually generated by Perl module called ExtUtils::MakeMaker. The complexity is caused by Perl having three different places to install code, called core, vendor and site, besides doing an installation mock-up for tests.
