-These commands will download and compile the program and execute all test cases to verify that it works correctly. After this you will have two files called `cubepro-encoder` and `cubex-encoder`. The first one will encode `.bfb` files into `.cubepro` files and the second one into `.cubex` files. *(In fact both encoders are identical. Only the name makes the difference, so do not rename them).*

 * Option 1: Just drop the `.bfb` file on the correct encoder program with your mouse.
 * Option 2: Run the encoder form the command line as follows:

+cube-encoder inputfile [outputfile]
 cubepro-encoder inputfile [outputfile]
+cube3-encoder inputfile [outputfile]
 cubex-encoder inputfile [outputfile]
 ```
-where the outputfile is optional. To encode a `.bfb` file, simply call `cubepro-encoder somefile.bfb` and it will create `somefile.cubepro`. Same for `cubex-encoder`, but with a `.cubex` file extension. If that doesn't suit you, you can specify any output file name you like.

 To decode an encoded `.cubepro` or `.cubex` file, just drop it on the `cube-decoder` program or run the following command. The file type to decode is automatically determined from the file extension of the input file.
