public class Encrypt extends TApplication<RuntimeException>
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
".tzp" or ".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
cp command of the Nzip class instead.
This class knows about the correct character sets for the various
flavours of ZIP compatible files.

Avoid repeating this method and updating the same archive file upon each call! This would degrade the overall performance from O(n) to O(m*n), where m is the number of new or modified entries and n is the number of all entries in the archive file!

runChecked(java.lang.String[]).
Prints a user readable error message to the error output stream
which was provided to the constructor if an occurs.
This method is run at least once and repeatedly called
until runChecked(java.lang.String[]) returns a non-negative integer for use as the
exist status of the VM.
After this method, the TApplication.sync() method is called in a
finally-block.
