# * Permit user-defined overwrite of variables via either explicit command-line
#   option or, if set, sourcing a shell-format "$FLUVIOL_CONFIG" file.
# * Recover from failure by running vanilla "fvwm-crystal" or "fvwm", instead,
#   if either reside in the current path. The user should be presented with a
#   prompt at which they will be asked to "Press any key...", so that they may
#   be made aware of this error prior to starting the LA.
