>DESCRIPTION</a></h1>
<p>The <em>PBC_COMPAT</em> file is used to maintain Parrot bytecode compatibility. 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>
