       USAGE  Here are some real life usages.

              Checks for xft support:
              if fvwm-config --supports-xft;
                then echo 1; else echo 0; fi

              fvwm-themes package checks for the correct fvwm version installed using:
              fvwm-config --version
              and tries to use the same installation directories:
              fvwm-config --bindir --mandir --fvwm-datadir

              A way to find the full path to the fvwm executable:
              echo `fvwm-config --bindir`/`fvwm-config --fvwm-exe`

              A way to start modules in perl:
              use lib `fvwm-config -p | tr -d '0`;
              use FVWM::Module;

              For a more human readable output, try:
              fvwm-config --info
