Package: ftp.debian.org Severity: normal The upstream stopped the project and removed repository years ago. This "HWP" document backend is still in premature state of a text-extractor so I don't think it worth to package.
And now there are the proprietary HWP viewer for Linux from Hancom which is the company making HWP. HWP itself is a proprietary doc format anyway so using the proprietary viewer is not ideal but not that bad.
