## Qt 5.12 lacks /usr/local/Cellar/qt/5.12.0/bin/qcollectiongenerator
## SEE: http://blog.qt.io/blog/2018/11/02/whats-new-qt-help/
## In addition, we have done some cleanups in version 5.12. We got rid of an
## ancient porting tool called qhelpconverter. We have merged the
## qcollectiongenerator tool into the qhelpgenerator, which now accepts both
## .qhp and .qhcp files as input and generates .qch and .qhc files, respectively.
