simplify API for --parents option

Hi,

If I want to copy all the html in assets directory and keep the directory structure inside dist directory I have to do the following command :

cpy '**/*.html' '../dist/' --cwd=assets --parents

I think the following command would be easier :

cpy 'assets/**/*.html' dist --parents

assets
├── index.html
├── robots.txt
└── test
    └── test.html

should return

dist
├── index.html
└── test
    └── test.html

not

dist
└── assets
    ├── index.html
    └── test
        └── test.html

npm -v
2.14.7

node -v
4.2.3

@schnittstabil you’re right, the first command is sufficient.

Maybe something in the doc :

$ cpy --help

  Usage
    $ cpy <source>... <destination> [--no-overwrite] [--parents] [--cwd=<dir>] [--rename=<filename>]

  Options
    --no-overwrite       Don't overwrite the destination
    --parents            Preseve path structure
    --cwd=<dir>          Working directory for source files
    --rename=<filename>  Rename all <source> filenames to <filename>

  <source> can contain globs if quoted

  Examples:
  Copy all png in src directory into dist except src/goat.png

    $ cpy 'src/*.png' '!src/goat.png' dist

  Copy all html inside src directory into dist and keep path structure

    $ cpy '**/*.html' '../dist/' --cwd=src --parents
