-VisualFAIL*
-===========
-
-Guest-system setup
-------------------
-For analysis with VisualFAIL*, the guest-system ELF binary must be compiled with
-debugging information (gcc/g++/clang/clang++ compiler flag "-g").  Note that
-debugging information quality/accuracy usually decreases with higher
-optimization levels.
-
-Database preparation
---------------------
-1. import-trace -t yourtrace.tc -i MemoryImporter
-2. import-trace -t yourtrace.tc -i FullTraceImporter
-3. import-trace -t yourtrace.tc -i ElfImporter -e yourbinary.elf --objdump $(which objdump) --sources
-
-Step 1 is the prerequisite to run the fault-injection campaign (you may use
-other importers as well, e.g., the RegisterImporter).  Steps 2 and 3 are
-required for VisualFAIL* to work.
-
-Setup
------
-Copy CONFIGURATION.php.dist to CONFIGURATION.php, edit it, and add your MySQL
-database credentials and the result-table name (usually starting with
-"result...", "echo SHOW TABLES | mysql yourdatabase" on the command line should
-give you the correct table name).
-
-(In a later version of VisualFAIL*, we will probably add automatic loading of
-~/.my.cnf if available.)
-
-Running and using VisualFAIL*
------------------------------
-./StartVF.sh requires PHP 5.4.0 or newer and uses its simple built-in web
-server.  You can connect to it by using http://localhost:1234 in a web browser
-on the same machine.  (If you need to connect from another machine, manually run
-"php -S 0.0.0.0:1234 -t .")
-
-Alternatively, VisualFAIL* can be set up using a "real" web server with a recent
-PHP version (5.x should suffice).
-
-Once the web server runs, you can use VisualFAIL*:
-
-- Pick a coloring (currently, only "Right margin" really makes sense), a
-  benchmark and a variant from the drop-down menus.  Click "Analyze".  Wait.
-
-- Enable the experiment result types you want to highlight by clicking them in
-  the top row.
-
-- Scroll down the left column with the disassembled machine code.  Instructions
-  that activated faults in the FI experiments, and led to one of the enabled
-  result types, are highlighted with red color.  The stronger the coloring, the
-  more experiments led to one of these failure modes.  (Actually, not the raw
-  number of actual experiments is used, but is weighted with the size of the
-  corresponding def/use equivalence class.)
-
-- Click one of the highlighted instructions to display a popup with the actual
-  result numbers, and the distribution among the different failure modes.
-
-- Pick a source-code file from the right-hand side pulldown to look into the
-  instructions generated from that file.  The right column now contains the
-  source code from that file, interspersed with the disassembled machine code
-  generated from it.  These disassembled machine-code lines are, just like in
-  the disassembly column, clickable to display details.  (The source-code lines
-  are currently not clickable, although the mouse cursor indicates otherwise.)
