 To use it normally, just drag an image file onto the program and select your orientation. Make sure there's a `colorSet.txt` file in the same directory as the program.

 You can also use it as a command-line program: `image2brick (-v | -h) [-c colorset_file] [-X] image_file`
 
 `-v` and `-h` options are the orientation that the macro will be in. The program requires you to specify at least one.
 
 `-c` specifies the colorset file to use. If not specified, image2brick will look for `colorSet.txt` in the current working directory.
 
 `-X` makes the program behave as a command-line interface. Since the vast majority of users of this program will use Windows, it operates as a normal program by default, pausing after messages and making the user select an orientation if one wasn't specified in the arguments. This option disables that and will simply display error/success messages and then immediately exit.

+
+For Linux, you get a single GCC build script. Have fun.
