  Small script for getting and build ArchLinux pkg from AUR
  Use: $(basename $0) [action] [pkgname]
   Where action is:
      get  <pkgname>   - download only.
      unpack <pkgname> - unpack archive
      make <pkgname>   - make package, unpack, if not unpacked,
                         download, if not downloaded.
      clean <pkgname>  - remove downloaded package and unpacked dir.
      build <pkgname>  - combine clean, get, unpack, make. Default action.
      help             - this screen.
  
  If you call script as '$(basename $0) <pkgname>' action 'build' is assumed.
  You can set system variable 'EDITPKG' to 1 for PKGBUILD edit ability.
