- Here are some real life usages.

  ## USAGE

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
```
