LYNX-DEV what is the difference between "--with-cfg-file" and "--libdir"

[Nelson Henry Eric]

I was surprised that with the option "--with-cfg-file=$HOME/.usr/lib",
the autoconf script made a new directory "lib" and put "lynx.cfg" there.
Could you explain the difference between setting "--libdir" and the
"--with-cfg-file" option.  Why do we need both?

        ./configure --exec-prefix=$HOME --bindir=$HOME/.lynx \
                --mandir=$HOME/.man \
                --with-cfg-file=$HOME/.usr/lib \
        [...]
        % make install
        ./mkdirs.sh /home/nelsonhe/lib
        mkdir /home/nelsonhe/lib
        [...]
        /usr/bin/install -c -m 644 lynx.cfg /home/nelsonhe/lib/lynx.cfg
