BTW what about something like this:

show_component_help(){
    component=$(echo $1 | sed -e 's/s$//' | tr "A-Z" "a-z")
    echo "  --enable-${component}s         enables all ${component}s"
    echo "  --disable-${component}s        disables all ${component}s"
    echo "  --enable-${component}=NAME     enables $component NAME"
    echo "  --disable-${component}=NAME    disables $compoenent NAME"
    echo "  --list-${component}s           show all available ${compoenent}s"
}

The only limitation is that the output is not aligned, we could use
printf from the coreutils for implementing that.

Regards.
