          Issue ID: 12765
           Summary: dmd needs a "--version" option like gdc
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: DMD
          Assignee: nobody@puremagic.com
          Reporter: tombrowder@acm.org

Currently the only way to query the installed version of dmd is to execute "dmd" with no options (or "dmd --help") and backup to see the version listed at the beginning of 68 help lines sent to stdout.

A "--version" option would be helpful for, among other things, scripting compiler usage.  Such an option should result in just the official version information sent to stdout, e.g.,

$ dmd --version
DMD64 D Compiler v2.065
