During release preparation (and other changes to PBC_COMPAT) the fingerprint of existing bytecode files is invalidated.</p> <p>This utility updates the version and fingerprint information in the bytecode, but can of course not assure that it will run correctly, when incompatible changes were done.</p> <p>If no options are given, a summary of the PBC header is printed to STDOUT.</p> <h1><a name="SEE_ALSO" >SEE ALSO</a></h1> <p>The <code>pbc_dump</code> utility does a much more thorough job of showing bytecode file headers.</p> </div> <!-- "mainbody" --> <div id="divider"></div> <div id="footer"> Copyright © 2002-2011, Parrot Foundation. </div> </div> <!-- "wrapper" --> </body> </html>
