>Description:

    "make all-depends-list" gives a nice overview of ports depending
    on this port, but it doesn't really give information who is
    depending on what:

	[/usr/ports/www/apache21] edwin at k7>make all-depends-list
	/usr/ports/converters/libiconv
	/usr/ports/devel/autoconf259
	/usr/ports/devel/gettext
	/usr/ports/devel/gmake
	/usr/ports/devel/libtool13
	/usr/ports/devel/libtool15
	/usr/ports/devel/m4
	/usr/ports/devel/p5-Locale-gettext
	/usr/ports/lang/perl5
	/usr/ports/lang/python
	/usr/ports/misc/help2man
	/usr/ports/security/openssl
	/usr/ports/textproc/expat2

    Where is devel/libtool15 needed by? Which port requires
    p5-Local-gettext? What is python doing in this story?

    This patch adds a new command called "all-depends-tree" which
    gives this information:

    [/usr/ports/www/apache21] edwin at k7>make all-depends-tree
    www/apache

    |\_security/openssl
    |  |\_lang/perl5
    |\_textproc/expat2
    |  |\_devel/libtool13

    Unfortunately I haven't been able to get rid of the header |
    where it isn't needed anymore, but for the rest it works!

    BUGS: 
    It doesn't keep track of what has been done, so ports with a
    huge dependency list take a long time before they are ready.
    Very long time sometimes. But they always finish!
