Editing Advanced Installation (section)

=What the installation process does=
The term "installation" in the title is used for brevity, and it actually covers all three steps: configuration, build and install.
# Configure: determine what tools are available on the system and how they should be used to built the software. Creates a layer of abstraction so that the build is platform-independent. Should ideally either solve or flag all problems, so that the build either works, or does not proceed at all.
# Build: compiles the software and documentation using RSFSRC/build as a "workplace"
# Install: moves the compiled executables and the documentation to the final locations in $RSFROOT, sometimes changing filenames. Kept separate from build so that it can be done by root, and to avoid build failures leaving junk files all over the system.
A successful installation will have created in <tt>$RSFROOT</tt> the following directories:
* <tt>bin/</tt>: executable programs
* <tt>doc/</tt>: auto-generated HTML documentation
* <tt>include/</tt>: header files with info on library procedures; fonts
* <tt>lib/</tt>: libraries and Python modules
