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
