-* `-i` run an interactive interpreter, executing each statement when entered

 * `[filename]` read from file instead of standard input
+* `/v`, `-v` print version string and exit

 Error handling and reporting is very basic, the parser only outputs "syntax error" and the interpreter can throw exceptions.

 ## Future work and status
 
-Don't be fooled by the 1.00+ version number—this is alpha-development quality software, in particular `this` and `super` do not work and fixing these is a priority. The project does contain a large chunk of working code which may be of interest to others wanting to use `flexc++` and `bisonc++` to create an interpreter, or who have worked through the book and want to gain greater knowledge of Modern C++. It is assumed that a lot of the existing code and be reused/adapted to create a JIT version in the style of `clox`.
