can also be defined. Many of them are only useful in very specific
cases, typical packages will therefore only use a few of them.

specifies the preferred installation method. Possible values are
+EUMM+ (for +Makefile.PL+ based installation using
+ExtUtils-MakeMaker+) and +MB+ (for +Build.PL+ based installation
using +Module-Build+). This variable is only used when the package
provides both installation methods.
* +PERL_FOO_CONF_ENV+/+HOST_PERL_FOO_CONF_ENV+, to specify additional
environment variables to pass to the +perl Makefile.PL+ or +perl Build.PL+.
