- <ul>
- <li> <code>/path/to/install/dir</code> is the directory which deal.II

- directory (e.g., <code>~/bin/deal.II</code>) or a directory
- such as <code>/usr/local</code> if you have root privileges.
- Another option is to use something like <code>`pwd`/../installed/</code> (note the
- backticks). Make sure the installation directory is not the same
- as the location where you unpacked <tt>deal.II/</tt>.
- </li>
-
- <li> If your machine has multiple processors, use <code>make
- -jN</code> in the last step, where <code>N</code> is the
- number of simultaneous build processes you want <code>make</code>
- to use at any given time. Allowing <code>make</code> to use
- more simultaneous build processes (assuming you have that many

- code itself, you can re-compile the library using only the
- last two commands above in the previously created build
