Hello,

Please add the following entry to /etc/mime.types:

application/vnd.portableweb+zip pweb

The media type is registered with IANA in the vendor tree:
https://www.iana.org/assignments/media-types/application/vnd.portableweb+zip

It is used for PortableWeb bundles: self-contained, ZIP-based interactive
documents (HTML, CSS, JavaScript and media in one file, opened by a
viewer). The format is described in the Internet-Draft
draft-selvaraj-portableweb-format and at https://github.com/portableweb/spec,
and is developed in the W3C Portable Web Content Format Community Group.

The file extension is .pweb. Like EPUB, the archive starts with an
uncompressed "mimetype" entry containing the media type string.

This mapping is also picked up by Android, whose MIME table is based on
Debian's mime.types. Today .pweb files are reported there as
application/octet-stream or as ZIP archives, so they can't be told apart
from other files.

Thank you,
Omprakash Selvaraj
