/**
* Encrypts the contents of the file provided as the first argument
* into the RAES file provided as the second argument for the main method.
*
* Please note that you should not use this utility to encrypt a plain
* ZIP file to an RAES encrypted ZIP file (usually a files with a
* {@code ".tzp"} or {@code ".zip.rae"} suffix).
* This is because RAES encrypted ZIP files use the "UTF-8"
* as their character set, whereas plain ZIP files use "IBM437",
* a.k.a. "CP437".
* To encrypt a plain ZIP file to an RAES encrypted ZIP file, use the
* {@code cp} command of the {@link Nzip} class instead.
* This class knows about the correct character sets for the various
* flavours of ZIP compatible files.
