Hi Mandy,

Regarding the command line arguments of jdeps, would it not be more consistent to re-use the same classpath related arguments as javac/java/javap/javah "-c" becomes "-cp" "--classpath" becomes "-classpath" ?

jdeps follows the GNU-style options which is different than the JDK style. We discussed this issue about consistency and familiarity [1].
After using jdeps for some time, I admit that I find it hard to switch to the new -c short option (and confusing too) but relatively easy to move to --classpath option. Mixing both GNU-style and JDK-style inconsistently adopting GNU style is not a good thing while GNU style is the direction we are going (e.g. pack200 follows GNU style).

This adds jdeps --format=dot option to print the output in dot-style format that can be taken to generate a dependency graph.

Webrev at: http://cr.openjdk.java.net/~mchung/jdk8/webrevs/8015912/webrev.00/ This also extends --verbose option to take an optional argument ("class" and "package") to replace the --verbose-level option and cleans up PlatformClassPath to use java.nio.file. thanks Mandy
