- arch_pkgname :: String
 The name of the package. This has be a unix-friendly name
 as it will be used in the package filename.
- arch_pkgver :: Version
 The version of the software as released from the authorii
  (e.g. 2.7.1).
- arch_pkgrel :: !Int
 This is the release number specific to the Arch Linux
 release. This allows package maintainers to make updates to
 the packages configure flags, for example. A pkgrel of 1
 is typically used for each upstream software release and is
 incremented for intermediate PKGBUILD updates.
- arch_pkgdesc :: String
 This should be a brief description of the package and its
 functionality. Try to keep the description to one line of text.
- arch_arch :: ArchList ArchArch
 Defines on which architectures the given package is
 available (e.g. arch=(i686 x86_64)).
- arch_url :: String
 This field contains a URL that is associated with the software
 being packaged. This is typically the projects website.
- arch_license :: ArchList License
 This field specifies the license(s) that apply to the package.
 Commonly-used licenses are found in usrsharelicensescommon. If
 you see the packages license there, simply reference it in the
 license field (e.g.  license=(GPL)). If the package provides a
 license not found in usrsharelicensescommon, then you should
 include the license in the package itself and set
 license=(custom) or license=(custom:LicenseName). The license
 should be placed in $pkgdirusrsharelicenses$pkgname when
 building the package. If multiple licenses are applicable for a
 package, list all of them: license=(GPL FDL).
- arch_makedepends :: ArchList ArchDep
 An array of packages that this package depends on to build, but are
 not needed at runtime. Packages in this list follow the same format
 as depends.
- arch_depends :: ArchList ArchDep
 An array of packages that this package depends on to run. Packages
 in this list should be surrounded with single quotes and contain at
 least the package name. Entries can also include a version
 requirement of the form nameversion, where  is one of five
 comparisons: >= (greater than or equal to), <= (less than or equal
 to), = (equal to), > (greater than), or < (less than).
- arch_source :: ArchList String
 An array of source files required to build the package. Source
 files must either reside in the same directory as the PKGBUILD
 file, or be a fully-qualified URL that makepkg will use to download
 the file. In order to make the PKGBUILD as useful as possible, use
 the $pkgname and $pkgver variables if possible when specifying the
 download location. Any files that are compressed will automatically
 be extracted, unless found in the noextract array listed below.
- arch_md5sum :: ArchList String
 This array contains an MD5 hash for every source file specified in
 the source array (in the same order). makepkg will use this to
 verify source file integrity during subsequent builds. To easily
 generate md5sums, run makepkg -g >> PKGBUILD. If desired, move
 the md5sums line to an appropriate location.  NOTE: makepkg
 supports multiple integrity algorithms and their corresponding
 arrays (i.e. sha1sums for the SHA1 algorithm); however, official
 packages use only md5sums for the time being.
- arch_build :: [String]
 The build hook
- arch_package :: [String]
 The packaging hook
- arch_install :: Maybe String
 Specifies a special install script that is to be included in the package. This
 file should reside in the same directory as the PKGBUILD, and will be copied
 into the package by makepkg. It does not need to be included in the source
 array (e.g.  install=pkgname.install).
- arch_options :: ArchList ArchOptions
 This array allows you to override some of makepkgs default behavior when
 building packages. To set an option, just include the option name in the
 options array. To reverse the default behavior, place an ! at the front of
 the option. Only specify the options you specifically want to override, the
 rest will be taken from makepkg.conf(5).  NOTE: force is a special option only
 used in a PKGBUILD(5), do not use it unless you know what you are doing.
