# The page method allows options to be set for a given source path, regex, or glob.
# Options that may be set include layout, locals, andx ignore.

# @example
# page '/about.html', layout: false
# @example
# page '/index.html', layout: :homepage_layout
# @example
# page '/foo.html', locals: { foo: 'bar' }
#
# @param [String, Regexp] path A source path, or a Regexp/glob that can match multiple resources.
# @params [Hash] opts Options to apply to all matching resources. Undocumented options are passed on as page metadata to be used by extensions.
# @option opts [Symbol, Boolean, String] layout The layout name to use (e.g. `:article`) or `false` to disable layout.
# @option opts [Boolean] directory_indexes Whether or not the `:directory_indexes` extension applies to these paths.
# @option opts [Hash] locals Local variables for the template. These will be available when the template renders.
# @option opts [Hash] data Extra metadata to add to the page. This is the same as frontmatter, though frontmatter will take precedence over metadata defined here. Available via {Resource#data}.
