This plugin attempts to be a cross between the
Pod::Weaver::Section::Template manpage and the
Dist::Zilla::Plugin::GenerateFile manpage without the generation of extra
files.

The values of text are concatenated and variable names with matching values
on the distribution are interpolated. Specifying the heading level allows
to write down a rather long section of POD text without need for extra
files. For example:

[GenerateSection / FEEDBACK]
head = 1
[GenerateSection / Reporting bugs]
head = 2
text = Please report bugs when you find them. While we do have a mailing
text = list, please use the bug tracker at {{$bugtracker_web}}
text = to report bugs
[GenerateSection / Homegape]
head = 2
text = Also, come check out our other projects at
text = {{$homepage}}
