Please port to Qt6. There is a rejected port available.
Note that kchmviewer is currently scheduled for autoremoval due to is
Qt5 WebEngine dependency.

Yup.

I don't plan to add this rejected +556 -1198 to the package and I have no
interest in porting it myself, at least manually. I could ask an LLM to do
a better job that the submitter's LLM and then put *that* into the
package, but then I already have a local 700 line Rust chmlib+gtk4+webkit6
CHM viewer I had an LLM write as a test for LLM one-shotting capabilities
half a year ago in case I ever need to read a CHM.

This day would come and I planned to RM the package if there are no other
options if the upstream doesn't have Qt6 at that point.
