/**
 * If a prefix is given, it will be removed from the entry's path. This also turns absolute paths
 * into relative paths (e.g., /usr/bin/bash will become usr/bin/bash, same as unzip's default
 * behavior) and normalizes the paths (foo/../bar////baz will become bar/baz). Note that this
 * could cause collisions, if a zip file had one entry for bin/some-binary and another entry for
 * /bin/some-binary./*w w w.  j a  va2s. c o  m*/
 *
 * Note that the prefix is stripped to move the files up one level, so if you have an entry
 * "foo/../bar" and a prefix of "foo", the result will be "bar" not "../bar".
