.Sh NAME
.Nm sushi
.Nd a menu based system administration tool
.Sh SYNOPSIS
.Nm
.Op Ar quickname
.Sh DESCRIPTION
The
.Nm
tool gives the user a menu of various system administration tasks that 
may be performed on the system.  It is designed to be simple enough for a 
novice to use, and quick enough to help seasoned users perform more 
complex tasks with ease.
.Pp
It is also designed to be easily extended and customizable by the user or 
administrator.  The menus themselves consist of a number of flat ascii 
files which are parsed by the
.Nm
engine when run.  Commands are actually scripts written by the 
administrator, and executed from the menu heirarchy.  It is possible to 
have multiple heirarchies, and even ones private to a particular user on 
the machine.  These hierarchies are all merged for the user at run-time 
into a single menu system.
.Pp
The following option is available:
.Bl -tag -width "quickname"
.It Ar quickname
This option allows the user to jump directly to a known submenu or function
within
.Nm .
It can be used to avoid the need to navigate deeply nested menus, when the
end destination is known.
.El
.Sh ENVIRONMENT
The following environment variables are utilized by
.Nm :
.Bl -tag -width "PKG_PATH"
.It Ev LANG
Determines the user's current language setting.
.It Ev PKG_PATH
This is the default URL for binary packages used when fetching lists 
of packages available to download.  It is also used when actually 
downloading those packages.  It defaults to:
ftp://ftp.netbsd.org/pub/NetBSD/packages
.El
.Pp
There may be other environment variables utilized by various scripts in the
.Nm
menu hierarchy.  This manual page cannot account for those environment 
variables, however they should be detailed in the help files for each menu.
.Sh FILES
.Bl -tag -width "sushi"
.It Pa /etc/sushi.conf
This file is used by sushi to override the default locations searched for 
menu hierarchies.  It consists of a keyword, followed by instructions.
To override the default searchpaths in
.Nm
you would issue the keyword
.Sq searchpath
followed by a directory name, one per line, that will be searched, in order,
for menu hierarchies.  Each directory name must be preceeded by the
.Sq searchpath
keyword. It is not an error to have a non-existent directory listed in
this file, as they will simply be skipped over.  The default list of
directories searched is printed below, in order: 
.It Pa /usr/share/sushi
.It Pa /usr/pkg/share/sushi
.It Pa /usr/X11R6/share/sushi
.It Pa /etc/sushi
.It Pa $HOME/sushi
The $HOME/sushi path, is allways searched, and does not need to appear in 
the
.Pa /etc/sushi.conf
file.  The
.Pa /etc/sushi.conf
file will not be parsed for environment variables such as $HOME, so it 
would likely be an error to include it there.
.Pp
The
.Pa /etc/sushi.conf
file may also include key bindings, which will override the default use
of function keys in
.Nm .
These may be desired in situations where function keys are not available, or
are not desirable because of a window-manager binding.  The format for
binding a key is:
.It bind F1 ^T ^T=Help
In the above example, we have rebound the
.Sq F1
key to Control-T.  The final keyword is the message that will appear at the
bottom of your screen, to remind you which keys are bound to which
functions.  There can be no whitespace in the key description.
The syntax of the new key binding must either be an ascii character
preceeded by a caret
.Dq ^
to signify a control modifier, a function key, such as
.Sq F9
or a single ascii character.  It is not possible to bind Alt or Meta keys,
nor is it possible to bind a modified function key, such as control-F1.
.El
.Sh EXAMPLES
.Pp
Most of the actual usage of
.Nm
is documented in the internal help files, such as commands, and keystrokes
that are used to navigate the menus.  There is also full documentation in
the help pages on writing your own menus.  In order to access help, you 
may hit the F1 key at any time, and if help is available for the current 
menu, it will be displayed.  It is advised that the user read the help 
file from the main menu, as it contains most of the navigation, and basic 
concepts of the
.Nm
engine.

.Xr rc.conf 5 ,
.Xr intro 8 .
.Sh BUGS
At the time of this writing, there are a number of display glitches 
which are currently being worked on.  In addition there are some failure 
modes that
.Nm
does not handle well, such as not recieving output from an escript field.
.Pp
At the time of this writing, the F6 option, to display the current command
before running it, does not work.
