Description
   Install manually from source
       In most cases, you just want to install the entire library.  To
       install all the files in the default system directories (per GNU
       guidelines), use:

           $ make               # optional
           $ sudo make install
           $ make installcheck  # optional

       You can install in parallel if you want.  A few features can be
       used to tweak the install.  To get some help, run:

           $ make help
