This is an effort to create a propper snippets manager for vis_,
eventually as a replacement for vim's UltiSnips or something
of that kind.

Originally based on
https://src.adamsgaard.dk/dotfiles/file/.config/vis/plugins/snippets.lua.html
by Anders Damsgaard (https://src.adamsgaard.dk/). That file
has not been licensed, but I hope the MIT/X11 license does
not offend anybody.

Eventual dream goal is to be compatible with the Honza’s
vim-snippets_.

After installation to ``~/.config/vis/plugins/vis-snippets`` Add definition of snippets in this style::

    snip = require('plugins/vis-snippets')
    snip.snippets = {
        fdup = '%python_expand %fdupes %{buildroot}%{$python_sitelib}',
        nopy = '%define skip_python2 1',
        patch = [[
    # PATCH-{FIX|FEATURE}-{OPENSUSE|SLE|UPSTREAM} name-of-file.patch bsc#[0-9]+ mcepl@suse.com
    # this patch makes things totally awesome
    Patch0:     <1>
        ]]
    }
    snip.init()
