   3 # This procedure determines the PKG_OPTIONS that have been in effect
   4 # when the package ${pkgbase} has been built. When the package is not
   5 # yet installed, the current PKG_OPTIONS are queried.
   6 #
   7 # Parameters:
   8 #       pkgbase
   9 #               The basename of the package.
  10 #
  11 # Returns:
  12 #       PKG_BUILD_OPTIONS.${pkgbase}
  13 #               The build options of the package.
  14 #
  15 # Example:
  16 #       pkgbase := wine
  17 #       .include "../../mk/pkg-build-options.mk"

  26 # avoids dealing one case.
