Install-progress reporting 
--------------------------

If the apt options: "APT::Status-Fd" is set, apt will send status
reports to that fd. The status information is separated with a ':',
there are the following status conditions:

status = {"pmstatus", "dlstatus", "conffile-prompt", "error", "media-change" } 

The reason for using a fd instead of a OpProgress class is that many
apt frontend fork a (vte) terminal for the actual installation.

The reason to do the mapping and l10n of the dpkg states to human
readable (and translatable) strings is that this way the translation
needs to be done only once for all frontends.


pmstatus
--------
Status of the package manager (dpkg). This is send when packages
are installed/removed.
pmstatus:pkgname:TotalPercentage:action-description

PkgName = the name of the package
TotalPercentage = the total progress between [0..100] 
description = a i18ned human readable decription of the current action


Example:
# ./apt-get install -o APT::Status-Fd=2 3dchess >/dev/null
pmstatus:3dchess:20:Preparing 3dchess
pmstatus:3dchess:40:Unpacking 3dchess
pmstatus:3dchess:60:Preparing to configure 3dchess
pmstatus:3dchess:80:Configuring 3dchess
pmstatus:3dchess:100:Installed 3dchess

pmerror
-------
pmerror:deb:TotalPercentage:error string

Example:
pmerror: /var/cache/apt/archives/krecipes_0.8.1-0ubuntu1_i386.deb : 75% : trying to overwrite `/usr/share/doc/kde/HTML/en/krecipes/krectip.png', which is also in package krecipes-data 


pmconffile
----------
pmconffile:conffile:percent:'current-conffile' 'new-conffile' useredited distedited


media-change
------------
media-change:medium:drive:human-readable string

example:
media-change: Ubuntu 5.10 _Breezy Badger_ - Alpha i386 (20050830):/cdrom/:Please insert the disc labeled: 'Ubuntu 5.10 _Breezy Badger_ - Alpha i386 (20050830)' in the drive '/cdrom/' and press enter.


dlstatus
--------
dlstatus:AlreadDownloaded:TotalPercentage:action-description

AlreadyDownloaded = the number of already downloaded packages
TotalPercentage = the total progress between [0..100] 
description = a i18ned human readable decription of the current action

Example:
dlstatus:1:9.05654:Downloading file 1 of 3 (4m40s remaining)
dlstatus:1:9.46357:Downloading file 1 of 3 (4m39s remaining)
dlstatus:1:9.61022:Downloading file 1 of 3 (4m38s remaining)
