Usage

From source file:org.hecl.jarhack.JarHack.java

/**
 * The <code>substHecl</code> method takes the filenames of two
 * .jar's - one as input, the second as output, in addition to the
 * name of the application.  Where it counts, the old name (Hecl,
 * usually) is overridden with the new name, and the new .jar file
 * is written to the specified outfile.  Via the iconname argument
 * it is also possible to specify a new icon file to use.
 *
 * @param infile a <code>FileInputStream</code> value
 * @param outfile a <code>String</code> value
 * @param newname a <code>String</code> value
 * @param iconname a <code>String</code> value
 * @exception IOException if an error occurs
 *///from   w ww.j  a  va2  s.  co  m
