One goal is obviously choice of packaging and hence availability of more packages. Also this gives maintainers a chioce to continue builing packages for GNU in the format they are already familiar with. The second goal is to demonstrate the flexibility GNU offers in implementing functionality in filesystems (open/read/write interface).
## Why?
+
* The GNU Hurd provides a lot of advanced features and functionalities. We aim to exploit those features.
* Combining translators with UnionFS gives a very exciting package manager.
* We could use the good features of existing packaging systems like deb, rpm, ebuilds, ports ... plus unionfs and hurd translator is a compelling compination.

With the increased flexibility in implementing filesystems as per the requirements, we can implement the functionality similar to apt-get, emerge or yum... (dependency tracking, versions tracking...) in the filesystem itself.
## What?
+
* Have a basic filesystem based package manager
* Write translators to convert between GNU's packaging format and the existing one's like rpm, deb ...
## How?
+
* Installtion of a package is just drag the pacakage (be it a tgz, rpm, deb or an exe) and drop it to the package manager.
* apt-cache search vim --> ls -al /packages/meta/ |grep vim
* apt-get install vim --> install vim
Just a sample script.

## Initial idea

A bit complex than the earlier scheme but it is more exciting and we can look at this schem seriously once we have the simple scheme working.
-All packages are installed at
-<pre>
-/packages/binary/<packagename>/<packageversion>
-</pre>
+All packages are installed at
+`/packages/binary/<packagename>/<packageversion>`.
For eaxmple vim 6.4 version can be installed from source like
-<pre>
-# cd vim64
-# ./configure --prefix=/packages/binary/vim/6.4
-# make
-# make install
-</pre>
+
+ # cd vim64
+ # ./configure --prefix=/packages/binary/vim/6.4

Now if you have another vim version, say 7.0 then just follow the steps
-<pre>
-# cd /packages/source/vim
-# CP /<pathtovimtarball>/vim-7.0.tar.bz2
-# tar -jxvf vim-7.0.tar.bz2
-# mv vim70 7.0
-# ./configure --prefix=/packages/binary/vim/7.0
-# make
-# make install

+ # ./configure --prefix=/packages/binary/vim/7.0
+ # make

You have 2 versions of vim and how can you sepcify which one is the current version? You can symlink the current version to select the version you would like to see as default

-# ln -s /packages/binary/vim/7.0 /packages/vim/current

Dependency information is stored as a symbolic link to the required packages in a subdirectory called depends.
