11.8.3 Packages providing a terminal emulator

Packages that provide a terminal emulator for the X Window System which meet the crite 

ria listed below should declare in their control data that they provide the virtual package

x terminal emulator

. They should also register themselves as an alternative for

/usr

/bin/x terminal emulator

, with a priority of 20.

To be an

x terminal emulator

, a program must:

  Be able to emulate a DEC VT100 terminal, or a compatible terminal.

  Support the command line option

 e

command

, which creates a new terminal window

6

and runs the specified command, interpreting the entirity of the rest of the command line

as a command to pass straight to exec, in the manner that

xterm

does.

  Support the command line option

 T

title

, which creates a new terminal window

with the window title title.

11.8.4 Packages providing a window manager

Packages that provide a window manager should declare in their control data that they pro 

vide the virtual package

x window manager

. They should also register themselves as an

alternative for

/usr/bin/x window manager

, with a priority calculated as follows:

  Start with a priority of 20.

  If the window manager supports the Debian menu system, add 20 points if this support

is available in the package's default configuration (i.e., no configuration files belonging

to the system or user have to be edited to activate the feature); if configuration files must

be modified, add only 10 points.

  If the window manager complies with The Window Manager Specification Project

(

http://www.freedesktop.org/Standards/wm spec

), written by the Free Desk 

top Group (

http://www.freedesktop.org/

), add 40 points.

  If the window manager permits the X session to be restarted using a different window

manager (without killing the X server) in its default configuration, add 10 points; other 

wise add none.

11.8.5 Packages providing fonts

Packages that provide fonts for the X Window System

7

must do a number of things to ensure

that they are both available without modification of the X or font server configuration, and that

they do not corrupt files used by other font packages to register information about themselves.

1 Fonts of any type supported by the X Window System must be in a separate binary pack 

age from any executables, libraries, or documentation (except that specific to the fonts

6

 New terminal window  does not necessarily mean a new top level X window directly parented by the win 

dow manager; it could, if the terminal emulator application were so coded, be a new  view  in a multiple document

interface (MDI).

For the purposes of Debian Policy, a  font for the X Window System  is one which is accessed via X protocol

requests. Fonts for the Linux console, for PostScript renderers, or any other purpose, do not fit this definition. Any

tool which makes such fonts available to the X Window System, however, must abide by this font policy.
