tsshbatch / TODO

  - Multiple hostfiles can now be passed via the -i option.  The
    argument can be the name of a single file or a quoted list of
    files.  The option can appear on the command line multiple times.
    -H and -i can be used together to create custom host lists.

  - The -L option will list all (if any) host- and command files found
    on their respective search paths.

  - The -W option will write out the inventory of hosts that would be
    processed if you actually executed the program, and then
    terminates.  This works only in test mode.  This allows you
    to embed tsshbatch in external shell scripts like this:

       for server in $( -i devserverlist -uatserverlist -W)
         ssh $server

    Why?  Because tsshbatch has lots of powerful ways to maintain
    inventories of hosts and combine them through includes and
    multiple command line arguments.  The -W option makes it
    convenient for external programs to make use of those inventory


  - The -H option can now appear on the command line multiple times
    thereby creating an aggregate list of all hosts named therein.

  - Hostfiles must now be passed as an argument of -i.  This was
    done to provide a consistent way of passing multiple host
    files on the commandline.


  - File transfers now properly honor the -s (silent output) flag.


  - Options for searching all the command files and hostlistfiles

  - File Xfer: Allow from within cmd files.

  - Interactive shell?


  - Show incremental output as program executes

  - File Xfer: Renaming - Cmdfile?

  - File Xfer: Globing - what about dirs, do we recurse? - Cmdfile?

  - implement sudoers Mode:

    - Capture bad password
    - Capture failed command output
    - Write the server noise, as it appears to stderr for debug purposes
    - Note in docs: In this mode it will HANG waiting for interactive input.
    - Note in docs: There is no separation between stdout and sterr in this mode
