How are these updated? Wouldn't it be better to integrate them with the build process?

A CHM is already included with D, which also includes a Phobos reference, keyword index, and other things only possible because it is generated by a dedicated program (chmgen). It is also integrated with D's build process. I don't think we need two...

IMHO, it would be better to integrate something like http://manual.calibre-ebook.com/cli/ebook-convert.html into our build process for the .mobi and upload and link the CHM we already have.

Historically, links to 3rd-party resources have bitrotten rather quickly. For example, see how many links on http://www.digitalmars.com/d/dlinks.html still work.

Yes, it makes sense to host it on dlang.org and have it part of the build process. I see in posix.mak the d.tag target builds the chm file. I'll look into getting the epub built with ebook-convert and adding it and the chm to the rsync target.

Currently posix.mak can't build the CHM file, because the CHM program is Windows-only. It only creates d.tag, which is used by dman.

Thanks!

Has there been any followup? The download links are already dead and I agree with Vladimir we shouldn't have 2 chms with similar content.
