In commit 071d5a84 I pushed a patch to restore the Help handbook
for TDEPowersave. Apparently those files got lost in the shuffle
when converting to cmake.
I presume the same changes are needed for KPowersave, but I don't
have a HAL based system to compile KPowersave. To somebody who does
and is interested in restoring the Help handbook to KPowersave, you
should be able to copy the patch, modify for naming differences,
and then push to git.
