Instructions on using Expresso:

1. Make sure the file you wish to test is saved as a simple text document (for example,
   in Notepad or something similar) and is in the same folder as your Expresso application.

2. On a PC, double click on "expressoPC.exe" to launch the application. On a Mac, 
   double click on "expressoMac".

3. In the window that pops open, enter the exact name of your text file, including any
   extensions.

4. Go through the list of errors, if any. Please keep in mind that although this program
   was designed to be (we hope) helpful, it is not infallible. There are errors that it
   won't catch. Its goal is to warn you of common errors that the compiler does not explain
   very well. Ideally, it should be run before the code is compiled, so that you can correct
   the errors it detects before tackling more unusual problems (or before the compiler 
   can confuse you).

5. There is one known bug in the program: when it comes across a for loop, it usually thinks
   you have extra opening and closing parentheses on that line. So if you get an extra
   parenthesis message on a line that begins a for loop, please double-check for yourself
   and ignore the error if it's incorrect.

6. When you're done, exit the application. This can be accomplished by pressing 'e' and 
   'enter' in the application window on PCs and with a File->Quit on Macs.
