Each mask is appended to DOTROOT to create an alternative DOTROOT path,
and finally to link target.  Therefore, you can have shared structure
like this:

    dotroot/fooapp
    dotroot/barapp
    dotroot.config/janeapp
    dotroot.config/aliceapp
    dotroot.local/share/janeapp
    dotroot.local/share/fooapp

The first two examples work just like before, but if masks ".config" and
".local/share" are defined, the rest is treated specially.  Final
mapping looks like this:

    ~/.fooapp -> dotroot/fooapp
    ~/.barapp -> dotroot/barapp
    ~/.config/aliceapp -> dotroot.config/aliceapp
    ~/.config/janeapp -> dotroot.config/janeapp
    ~/.local/share/fooapp-> dotroot.local/share/fooapp
    ~/.local/share/janeapp -> dotroot.local/share/janeapp

This allows for quite a good flexibility of how you define your shared
structure to reflect habits of many common applications while retaining
ease of deplyment.

Note that:

*   `.config` and `.local/share` masks are defined by default

*   you can provide your own by using one or more `--mask` arguments;
    this, however, removes the default ones

**Warning:** Potential clases between masks like ".local/share and
".local" are **not** solved within script.  Avoid that.  Currently
it's an undefined behavior.

Simple sed filter to padd all by 4 spaces for inclusion into e-mail
and the likes.

In order to make it work, you need to:

*   install Perl::Critic

*   add bin/perl_critic to your path

    Note that `perlcritic` script name is already taken by wrapper
    script that comes with Perl::Critic itself

*   show trailing space as well
*   use Unicode characters
*   toggle with <F2>

Because using alias pollutes ps -f output.

*   if dotfiles are shared by git, it will ignore
    all files under dotfiles/git-universe/private

*   if you use other sharing mechanism, you need
    to exclude these files other way
