# The of the methods defined in this file and the order of the methods is
# relevant for the documentation generated on the
# CocoaPods/cocoapods.github.com repository.
#-------------------------------------------------------------------------#
# A specification describes a version of Pod library. It includes details
# about where the source should be fetched from, what files to use, the
# build settings to apply, and other general metadata such as its name,
# version, and description.
#
# ---
#
# A stub specification file can be generated by the [pod spec
# create](http://guides.cocoapods.org/terminal/commands.html#pod_spec_create) command.
#
# ---
#
# The specification DSL provides great flexibility and dynamism. Moreover,
# the DSL adopts the
# [convention over configuration](http://en.wikipedia.org/wiki/Convention_over_configuration)
# and thus it can be very simple:
#
# Pod::Spec.new do |spec|
# spec.name = 'Reachability'
# spec.version = '3.1.0'
# spec.license = { :type => 'BSD' }
# spec.homepage = 'https://github.com/tonymillion/Reachability'
# spec.authors = { 'Tony Million' => 'tonymillion@gmail.com' }
# spec.summary = 'ARC and GCD Compatible Reachability Class for iOS and OS X.'
# spec.source = { :git => 'https://github.com/tonymillion/Reachability.git', :tag => 'v3.1.0' }
# spec.source_files = 'Reachability.{h,m}'
# spec.framework = 'SystemConfiguration'
# spec.requires_arc = true
# end
#

# @!group Root specification
#
# A ‘root’ specification stores the information about the specific
# version of a library.
#
# The attributes in this group can only be written to on the ‘root’
# specification, **not** on the ‘sub-specifications’.
#
# ---
#
# The attributes listed in this group are the only one which are
# required by a podspec.
#
# The attributes of the other groups are offered to refine the podspec
# and follow a convention over configuration approach. A root
# specification can describe these attributes either directly of
# through ‘[sub-specifications](#subspec)’.
#-----------------------------------------------------------------------#
# @!method name=(name)
#
# The name of the Pod.
#
# @example
#
# spec.name = 'AFNetworking'
#
# @param [String] name
# the name of the pod.
#
root_attribute :name,

#------------------#

# [semantic versioning](http://semver.org).

# @example
#
# spec.version = '0.0.1'
#
# @param [String] version
# the version of the Pod.
#
root_attribute :version,

# @example
#
# spec.author = 'Darth Vader'
#
# @example
#
# spec.authors = 'Darth Vader', 'Wookiee'
#
# @example
#
# spec.authors = { 'Darth Vader' => 'darthvader@darkside.com',
# 'Wookiee' => 'wookiee@aggrrttaaggrrt.com' }

# @!method social_media_url=(social_media_url)
#
# The URL for the social media contact of the Pod, CocoaPods web
# services can use this.
#
# For example, the @CocoaPodsFeed notifications will include the
# Twitter handle (shortening the description) if the URL is relative to
# Twitter. This does **not** necessarily have to be a Twitter URL, but
# only those are included in the Twitter @CocoaPodsFeed notifications.
#
# @example
#
# spec.social_media_url = 'https://twitter.com/cocoapods'
#
# @example
#
# spec.social_media_url = 'https://groups.google.com/forum/#!forum/cocoapods'

# The URL for the docset for the Pod
#
# @example
#
# spec.docset_url = 'http://example.org/KFData/1.0.0/xcode-docset.atom'
#
# @param [String] docset_url
# the docset URL.
#

# The keys accepted by the license attribute.
#

# @!method license=(license)

# The license of the Pod.
#
# ---
#
# Unless the source contains a file named `LICENSE.*` or `LICENCE.*`,
# the path of the license file **or** the integral text of the notice
# commonly used for the license type must be specified.
#
# This information is used by CocoaPods to generate acknowledgement
# files (markdown and plist) which can be used in the acknowledgements
# section of the final application.
#
# @example
#
# spec.license = 'MIT'
#
# @example
#
# spec.license = { :type => 'MIT', :file => 'MIT-LICENSE.txt' }
#
# @example
#
# spec.license = { :type => 'MIT', :text => <<-LICENSE
# Copyright 2012
# Permission is granted to...
# LICENSE
# }
#
# @param [String, Hash{Symbol=>String}] license
# The type of the license and the text of the grant that
# allows to use the library (or the relative path to the file
# that contains it).

# @example Specifying a Git source with a tag. This is how most OSS Podspecs work.
#
# spec.source = { :git => 'https://github.com/AFNetworking/AFNetworking.git',

#
# **Note:** this means that these libraries *have* to specify the

# File patterns may contain the following wildcard patterns:
#
# ---
#
# ### Pattern: *
#
# Matches any file. Can be restricted by other values in the glob.
#
# * `*` will match all files
# * `c*` will match all files beginning with `c`
# * `*c` will match all files ending with `c`
# * `*c*` will match all files that have `c` in them (including at the
# beginning or end)
#
# Equivalent to `/.*/x` in regexp.
#
# **Note** this will not match Unix-like hidden files (dotfiles). In
# order to include those in the match results, you must use something
# like `{*,.*}`.
#
# ---
#
# ### Pattern: **
#
# Matches directories recursively.
#
# ---
#
# ### Pattern: ?
#
# Matches any one character. Equivalent to `/.{1}/` in regexp.
#
# ---
#
# ### Pattern: [set]
#
# Matches any one character in set.
#
# Behaves exactly like character sets in Regexp, including set negation
# (`[^a-z]`).
#
# ---
#
# ### Pattern: {p,q}
#
# Matches either literal `p` or literal `q`.
#
# Matching literals may be more than one character in length. More than
# two literals may be specified.
#
# Equivalent to pattern alternation in regexp.
#
# ---
#
# ### Pattern: \
#
# Escapes the next meta-character.
