dpkg help screen: may I suggest?



For your interest, I would suggest that a help screen along the lines
of the following would be more helpful, at least to myself, and
perhaps others.  This file is to be considered bogus, however, unless
someone corrects and extends it.  Mainly, I don't understand most of
these parameters; in particular, I don't use dselect or Packages to
install, since as far as I can tell this would require me to have
virtually the whole archive in place.

This is intended only to suggest what a more conventional --help
screen would look like.

I have also included a sample help screen for dpkg-deb using a similar format, 
which will also be deficient, for the same reasons.

electra:/home/lex#dpkg-deb --help
       dpkg:  Debian GNU/Linux package maintainance tool. 

Usage:  dpkg [-options] [--parameter [--subparameter]] 
                                [filename or .debfile name or -R]
  Most parameters and options have both long (GNU) and short forms.

    -h, --help     Types this screen.
    -v, --version  Types dpkg version and licensing information and exits.
    -l, --list     Types a helpful list of installed packages files and status.


Basic Package Maintainance:
 On .deb packagefiles
  -i, --install <.deb file name> ...  Install and configure a .deb packageile
      --unpack <.deb file name> ...   EXACTLY WHAT DOES THIS DO? 
  -A, --avail <.deb file name> ...    
      --contents <.deb file name> ... List of files in a .deb packagefile

 On installed or unpacked packages   dpkg -l -> listing of all installed packages.
      --configure <package name> ... Configures an unpacked package
      --configure -a, --pending      What this does
  -r, --remove                       Remove package, leave config files alone 
      --purge <package name> ...     Remove package and config files
      --purge  -a, --pending         Look for and remove unconfigured packages
  -s, --status <package-name> ...    Show info screen, status of installed package
  -L, --listfiles <package-name> ... List of files in an installed package
  -l, --list [<package-name-pattern> ...]  
  -S, --search       <filename-search-pattern> ...     
  -C, --audit | --yet-to-unpack                [What does this do?]
  --merge-avail | --update-avail <Packages-file>

 
Recursive Operations
  -i, --install    -R, --recursive <dir> ...
      --unpack     -R, --recursive <dir> ... 
  -A, --avail      -R, --recursive <dir> ... 


Operations on Unconfigured (Pending) Packages
  --purge (-a, --pending)            Seek and remove all unconfigured packages.
  

Operations based on Packages file.


For internal use:    (Perhaps include these only in dpkg-deb --help screen?).

USE `DSELECT' FOR USER-FRIENDLY PACKAGE MANAGEMENT.

Use `dselect' for user-friendly package management.  
Packages unpacked using `dpkg-deb --extract' will be incorrectly installed !
