I acknowledge the history of the digikam help handbooks, but I'm uncomfortable with that approach for Trinity.
Let's split the English component only and merge that directly into the existing Digikam sources. That is how all other apps are designed. I have already tested that.
The remaining languages can move to a new module, applications/digikam-doc-i18n.
Most users who do not speak i18n languages don't want to install all of those components just to obtain access to the digikam/showfoto handbooks. Further, as is common with all other Trinity apps, there should be a default handbook installed with the package. :)
I have this all tested.
I have a single patch to push for the existing Digikam, which will build the English handbooks for Digikam and Showfoto.
I have the proposed digikam-doc-i18n contents tested so only the i18n handbooks are built and installed. My digikam-doc-i18n files also include copies of the master admin and cmake files.
All I need now is for somebody to create a new module in the main repository named digikam-doc-i18n. With the new upstream module I can push the whole directory and we'll be done. I would create the new module myself but I don't know whether I have permissions to do that and I also don't know all that is involved.
Digikam and Showfoto handbooks standing by!
