=head1 The build file for Chemistry::Elements
This build file is a modulino; it works as both a build script and
a module.
To build the distribution, run this file normally:
% perl Makefile.PL
But, it's more interesting than that. You can load it with C<require>
and call C<arguments> to get the data structure it passes to
C<WriteMakefile>:
my $package = require '/path/to/Makefile.PL';
my $arguments = $package->arguments;
Note that C<require>-ing a file makes an entry in C<%INC> for exactly
that name. If you try to C<require> another file with the same name,
even from a different path, C<require> thinks it has already loaded
the file. As such, I recommend you always require the full path to the
file.
The return value of the C<require> is a package name (in this case,
the name of the main module. Use that to call the C<arguments> method.
Even if this distribution needs a higher version of Perl, this bit
only needs v5.8. You can play with the data structure with a primitive
Perl.
