Support for entry points that are not index.html pages #1289
Description
Is your feature request related to a problem? Please describe.
I would like to be able to generate a sitemap using sapper. This works for the build but can't currently be export because entry points are restricted to directories i.e. index.html pages.
Describe the solution you'd like
I want the --entry argument to detect file names with extensions and export them without attempting to add a /.
Describe alternatives you've considered
The only workaround I have found is to preload the sitemap.xml on another page that gets crawled by sapper export. This seems like a bit of a hack to me.
