title: Conventions for additional content of the manifest.mf file?
body: <p>Are there any conventions for the MANIFEST.MF file in a Java JAR beyond the <a href="http://download.oracle.com/javase/1.4.2/docs/guide/jar/jar.html" rel="nofollow">JAR specification</a>? Interesting information I might want to include are: Build date and other build information, SVN Revision, perhaps a description. I haven't found suggestions how to name the corresponding keys. Are there any de facto standards or at least common key names that are used in manifests for things that are not covered by the spec?</p>
