      0 ~>pkg_src_summary \ 
www/ap2-wsgi:PYTHON_VERSION_DEFAULT=23,PKG_APACHE_DEFAULT=apache2

Initial support for building src_summary for multi-variant packages (-m),
    new special artificial output field VARIANTS7 is supported.
    Unfortunately pkgsrc developers declined this idea

    http://mail-index.netbsd.org/tech-pkg/2008/07/20/msg001320.html

    VARIANTS7 because I hope they will change their mind.

  Example:

      0 ~>./pkg_src_summary -a 'VARIANTS7' www/ap2-wsgi
      PKGPATH=www/ap2-wsgi
      PKGNAME=ap22-py24-wsgi-1.3
   => VARIANTS7=PYTHON_VERSION_DEFAULT=25,24,23 \ 
PKG_APACHE_DEFAULT=apache2,apache22

      0 ~>./pkg_src_summary -a 'VARIANTS7' lang/lua     
      PKGPATH=lang/lua
      PKGNAME=lua-5.1.3nb1
   => VARIANTS7=

      0 ~>./pkg_src_summary -a 'VARIANTS7' www/php-apc        
      PKGPATH=www/php-apc
      PKGNAME=php5-apc-5.2.6.3.0.16
   => VARIANTS7=PHP_VERSION_DEFAULT=4,5
