     3 1. Determine the provenence of every file on my system.

     4 2. Always have an "undo" button.

     5 

     6 These criteria have evolved from my frustrations

     7 with my previous LFS system.

    10 User expreience:

    11 

    12 Suppose I want to install emacs.

    13 

    14 here's a sample terminal session

    15 

    16 $ pkg emacs "a text editor"

    17    > creating user emacs.

    18    > cd /pkg/emacs

    19 

    20 $ wget http://emacs.com/emacs.tar.bz2

    21    > downloaded emacs.tar.bz2

    22    

    23 $ unp emacs.tar.bz2; cd emacs; configure; 

    24      make install;

    25    > install stuff.. 

    26    

    27 $ hg st

    28    > a bunch of files are added

    29 

    30 1. Say I don't want emacs after all.

    31 $ hg purge; hg revert --all

    32 

    33 2. Complete emacs instilation

    34    > hg addr; hg commit -m "emacs." 

    35 

    36 (this commits as the emacs user)

    37 

    38 3. can examine provenance of information

    39 $ pkg-report emacs

    40    > package emacs owns the following files:

    41    >  emacs

    42    >  man/emacs 

    43    > ....

    44 

    45 4. see all the commits that the "emacs" user made.

    46 $ pkg-history emacs

    47   > <filtered mercurial log>

    48 

    49 5. remove a package in its entirety

    50 $ pkg-remove emacs

    51   > removed

    52   > <list of files>

    53
