Core configuration. This file is read as first initialization upon starting FVWM Window Manager. In fact, FVWM is invoked with -f /path/to/Main.fvwmconf to read it instead of default FVWM system configuration or user's ~/.fvwm/config. This invocation and configuration in Main.fvwmconf changes everything: it avoids ~/.fvwm if user has a plain (normal) FVWM setup, defines and redefines FVWM internal variables and sets NSCDE_ROOT, configures some core FVWM options (like DefaultIcon), defines main FVWM Read command wrapper f_ReadCfg, sets desktop names, reads NsCDE.conf depending if user has it, or system-wide one, defines StartFunction, DesktopSize, and then reads most of the files described in this documents, composing NsCDE FVWM configuration. Care must be taken NOT to read this file with f_ReadCfg, because it will end up in the endless CPU hogging loop because f_ReadCfg will be destroyed and recreated during it's own execution. This file should never be overridden in $FVWM_USERDIR. It is the init(8) of the NsCDE system.
