 The goal is also to explain what a user is installing and what the few lines in the build description do. Now they know the name, can search for similar names if they have another package manager or distro or can ask Google/Wikipedia. We often find many build receipts with cryptic shell code and to execute this unknown stuff with sudo is not comfortable. We would like to know what it does before hitting enter.

 .. HINT:: There are some dependencies for building GCC (``gmp``, ``mpfr`` and ``mpc``). If you have not installed them on your system, you can either build them manually or use the ``download_prerequisites`` script provided in the GCC source tree (recommended): ``cd /path/to/gcc/source/dir && ./contrib/download_prerequisites``.
 
 * First configure GHDL, specify GCC source directory and installation prefix (like  ``/usr/local`` or ``/opt/ghdl``).
-
 * Next, invoke ``make copy-sources`` to copy GHDL sources in the source directory.
-
 * Then, configure GCC. The list of ``--disable`` configure options can be adjusted to your needs. GHDL does not require all these optional libraries and disabling them will speed up the build.
-
 * Now, build and install GCC with ``make``.

 * Last, build and install GHDL libraries.
