The README is a bit out of date. Please go to http://cimulator.org to see a live demo.
First do a shallow clone of the repository :
git clone --depth 1 http://www.github.com/pallavagarwal07/iTS
If you want the executable to run from any directory (recommended) put a symlink to the executable in your path.
cd /usr/local/bin
sudo ln -s <PATH TO CLONED DIR>/its its
The executable its is run to start the program.
The following Flags are supported:
-i Specify the input file (default is stdin)
-o Specify the output file (default is stderr)
-c Specify the file with the code to be run (Default is assets/code.c)
-v Verbosity level (verbosity level is compounded)
-vv
-vvv
In case you feel that something is wrong with the program, or if it not working, run the test_suite in its directory.
