Mustache templating

The lerna-templater uses Mustache.js for templating. If the template directory contains files which ends with .mustache, the templater will render them with Mustache.js. After the rendering, the .mustache extension will be removed from the filename. For example: package.json.mustache will be saved as package.json.

Available tags:

• {{{name}}} - The name of the new package.
• {{{descriptio}}} - The description of the new package.
• {{{scope}}} - The scope of the new package.
• {{{packages}}} - The relative path of the packages (output) directory.
• {{{template}}} - The relative path of the template (input) directory.
• {{{version}}} - The version of the new package.
• {{{repoDir}}} - The relative path of the new package in the repository.
