i is to be used when you're working on a Perl module, are
located in some subdirectory of it and want to call ``make install''
in the top directory. It will go upwards the directory hierarchy
from where you are, looking
for ``Makefile'' or ``Makefile.PL'' and call ``make install'' or
``perl Makefile.PL; make install'' if it finds one.
