== 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 '`; use
FVWM::Module;

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