       App::Pinto::Command::roots - show the roots of a stack


       version 0.097


         pinto --root=REPOSITORY_ROOT roots [OPTIONS]



       This command lists the distributions that are the roots of the dependency tree that
       includes all the distributions in the stack.  In other words, it tells you which
       distributions or packages you would need to install from this stack to get all the other
       distribution in the stack.


       As an alternative to the "--stack" option, you can also specify the stack as an argument.
       So the following examples are equivalent:

         pinto --root REPOSITORY_ROOT list --stack dev
         pinto --root REPOSITORY_ROOT list dev

       A stack specified as an argument in this fashion will override any stack specified with
       the "--stack" option.  If a stack is not specified by neither argument nor option, then it
       defaults to the stack that is currently marked as the default stack.


           Format of the output of each record using "printf"-style placeholders.  Valid
           placeholders are:

             Placeholder    Meaning
             %p             Package name
             %P             Package name-version
             %v             Package version
             %y             Pin status:                     (!) = is pinned
             %a             Distribution author
             %f             Distribution archive filename
             %m             Distribution maturity:          (d) = developer, (r) = release
             %M             Distribution main module
             %h             Distribution index path [1]
             %H             Distribution physical path [2]
             %s             Distribution origin:            (l) = local,     (f) = foreign
             %S             Distribution source
             %d             Distribution name
             %D             Distribution name-version
             %V             Distribution version
             %u             Distribution url
             %%             A literal '%'

             [1]: The index path is always a Unix-style path fragment, as it
                  appears in the 02packages.details.txt index file.

             [2]: The physical path is always in the native style for this OS,
                  and is relative to the root directory of the repository.

           You can also specify the minimum field widths and left or right justification, using
           the usual notation.  The default format is "%a/%f".

       --stack NAME
       -s NAME
           List the roots of the stack with the given NAME.  Defaults to the name of whichever
           stack is currently marked as the default stack.  Use the stacks command to see the
           stacks in the repository.


       Install all modules in the stack in one shot:

         pinto -r /myrepo roots | cpanm --mirror-only --mirror file:///myrepo

       Generate a basic cpanfile that would install all modules in the stack:

         pinto -r /myrepo roots -f 'requires q{%M};' > cpanfile


       This list of roots produced by this command is not always correct.  Many Perl
       distributions use dynamic configuration so you can't truly know what distributions need to
       be installed until you actually try and install them.  Pinto relies entirely on the static
       META files to determine prerequisites.

       But in most cases, this list is pretty accurate.  When it is wrong, it typically includes
       too many distributions rather than too few.  At best, this will have no impact because
       your installer will have already installed them as prerequisites.  At worst, you may be
       installing a distribution that you don't really need.
