This is a fork of vtwm that is intended to keep track of the oficial sources, but uses a different, self contained, build system that depends only on posix shell, nawk and bmake. Synchronized with commit 70991cc from 2018-09-02 (1) (1): https://sourceforge.net/p/vtwm/code/ci/70991cca915cdd7b5da1f78d18fb97d5bc7dff96/
