Compiling

To compile and test the latest source code:

• open a command prompt or terminal in the parent folder of where you want to download NumeralConverter to

  git clone https://github.com/Walkman100/NumeralConverter.git
  cd NumeralConverter
  # on windows:
  compile
  numeralconverter -h
  # on linux:
  make
  mono numeralconverter.exe -h

• On Linux, either:

  • rename the file to numeralconverter to be able to just do mono numeralconverter -h
  • create a numeralconverter script in /usr/bin (or /bin) with the contents of:

    
    #!/bin/sh

mono /full/path/to/numeralconverter.exe $@

then `chmod 777` it and you should be able to just do `numeralconverter -h` from any folder.

## Program Usage
### Windows
You can download the [NumeralConverterWindows.bat](https://github.com/Walkman100/NumeralConverter/blob/master/VB/NumeralConverterWindows.bat) file and put it in the same folder as the executable to use the program without opening a command prompt first.

To use from the command prompt, from the program folder:
```sh
> numeralconverter -h
