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 'n'`; use FVWM::Module;

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