new
        my $intr = Alien::Build::Interpolate->new;

   add_helper
        $intr->add_helper($name => $code);
        $intr->add_helper($name => $code, %requirements);

   replace_helper
        $intr->replace_helper($name => $code);
        $intr->replace_helper($name => $code, %requirements);

   has_helper
        my $coderef = $intr->has_helper($name);

       Used to discover if a helper exists with the given name.  Returns the code reference.

   execute_helper
        my $value = $intr->execute_helper($name);

       This evaluates the given helper and returns the result.

   interpolate
        my $string = $intr->interpolate($template, $build);
        my $string = $intr->interpolate($template);

       This takes a template and fills in the appropriate values of any helpers used in the template.

       [version 2.58]

       If you pass in an Alien::Build instance as the second argument, you can use properties as well as helpers
       in the template.  Example:

        my $patch = $intr->template("%{.install.patch}/foo-%{.runtime.version}.patch", $build);

   requires
        my %requires = $intr->requires($template);

       This returns a hash of modules required in order to execute the given template.  The keys are the module
       names and the values are the versions.  Version will be set to 0 if any version is sufficient.

   clone
        my $intr2 = $intr->clone;

       This creates a clone of the interpolator.
