+In part 2, we also update the apps file. Instead of using shell script (simulate.sh), we use
+the equivalent python version (simulate.py). The new apps file now looks like this:
+
+-----
+localhost simulate simulate.py

+Swift does not need to know anything about the language an application is written in. The application 
+can be written in Perl, Python, Java, Fortran, or any other language.

 To run the script and view the output:
 -----
 $ cd ../part02
