  * <li>The purpose of these lines is just the standard BASH header. Additionally, we import a wrapper created for libcvautomation to make our job easier. Please note that this is the default directory for the wrapper, your installation may be different. Use the command <tt>locate libcvautomation_funcs</tt> to find it on your computer. The wrapper itself is a handful of macros used to make our job easy.
+ * <li>The \c set line will abort the test if an error is ever encountered - for example, no images are found.
  * <li>Changing any wrapper parameters should go after sourcing the wrapper functions. See \ref appendix_variables for more information.
