/*
NixOS support 2 fontconfig versions, "support" and "latest".
- "latest" refers to default fontconfig package (pkgs.fontconfig).
configuration files are linked to /etc/fonts/VERSION/conf.d/
- "support" refers to supportPkg (pkgs."fontconfig_${supportVersion}").
configuration files are linked to /etc/fonts/conf.d/
Configuration files are linked to /etc/fonts/${pkgs.fontconfig.configVersion}/conf.d/
This module generates a package containing configuration files and link it in /etc/fonts.
