Package dependency tree in pkg order

[Manoj Srivastava <srivasta@datasync.com>]

Hi guys,

	I have used the perl 5 modules contained in the pkg-order
 package to create two more utilities, like pkg-order, all the
 executables are merely small wrappers around the librarycalls.

 1) pkg-nodep -- List of packages that no other package pre-depends or
    depends on (optionally, recommends and/or suggestsd can be heeded
    as well). I learnt that I no longer need libc4 -- the other libs I
    no longer have packages dependent on are:

	 libbfd2.7.0.9 libbfd2.8 libbfd2.8.1-dev libc4 libc6-doc
	 libc6-pic libcgi-perl libcgi-pm-perl libdbi-perl
	 libdl1-altdev libdnd1-dev libelf0-dev libg++272-dbg
	 libg++272-dev libgdbm1-altdev libgdbmg1-dev libgif2-dev
	 libgpc2 libident libjpeg-dev libjpeg-progs libmagick-dev
	 libmsql1 libpam-dbg libpam-doc libpng0-dev libproc-dev
	 libpwdb-dbg libpwdb-doc libreadline2-altdev libreadlineg2-dev
	 libtclobjc1 libtiff3-dev libtiff3-gif libtool

 2) pkg-deptree (shows an list of dependencies like shown below; the
    problem, of course, is that a package may have multiple
    dependencies and dependents; unless we allow infinite duplication,
    one has to restrict how often a package appears. I allow a package
    to only appear as many times as needed, but it's dependants only
    appear under the first occurance (that is, the tree whose root is
    the package is expanded only once). This can be changed.


	I have yet to upload the package which has pkg-deptree, I'll
 do that soon. Is there any interest in these toys?
