34 /**
35  * A {@link Zip32Driver} which reads and writes Self Executable (SFX) ZIP32
36  * archives.
37  * <p>
38  * <b>Warning:</b> Modifying SFX archives usually voids the SFX code in the
39  * preamble!
40  * This is because most SFX implementations do not tolerate the contents of
41  * the archive to be modified (by intention or accident).
42  * When executing the SFX code of a modified archive, anything may happen:
43  * The SFX code may be terminating with an error message, crash, silently
44  * produce corrupted data, or even something more evil.
45  * However, an archive modified with this driver is still a valid ZIP file.
46  * So you may still extract the modified archive using a regular ZIP utility.
47  * <p>
48  * Instances of this class are immutable.
