-.TH SESSION 1
-.SH NAME
-session \- graphical interface for configuring tasks using
-.IR cpu (4)
-and
-.IR ns (1)
-resources
-.SH SYNOPSIS
-.B grid/session
-.SH DESCRIPTION
-.I Session
-allows the user to build up a single namespace from various different namespace resources and configure a set of commands to be executed within this namespace. The execution then takes place on one or more selected
-.IR cpu (4)
-resources.
-.PP
-Once started,
-.IR session
-presents a heirarchical view of currently registered resources (such as
-.IR ns (1))
-which export a Styx (see
-.IR intro (5))
-namespace. The top level displays the type of resource e.g.
-.BR 'CPU resource' ,
-whilst the second level shows the name of each individual resource. Descending futher down the tree will reveal the attributes of the selected resource. To mount a resource and see the namespace it exports, click mouse button 3 on the resource name. The view will switch to a split pane view displaying the resource namespace with directories listed on the left and all files in the current directory displayed on the right.
-.PP
-Clicking mouse button 3 on a file or directory will cause it to be added to the
-.I command
-or
-.I namespace
-list at the bottom of the window. Mouse button 3 is again used on items in either of these lists to display a menu containing the name of the resource on which they are located as well as the option to remove them. The
-.B Cmd
-and
-.B Ns
-buttons located at the top of the window toggle the view between the selected commands and the selected namespace. The
-.B Resources
-button returns to the initial view containing the currently registered resources and
-.B Refresh
-updates the list in case any resources have been added or removed.
-
-.SS The Command List
-This contains a list of all commands to be executed. Any arguments may be entered by clicking on the gap after
-.IR args :
-and typing into the box. Commands will be executed in order from top (first) to bottom (last).
-
-.SS The Namespace List
-This contains a list of all the directories to be imported in order to create the local namespace of the selected
-.IR cpu (4)
-resource(s). By default, several directories will be imported from the local machine. To select these, click button 3 on
-.B import local namespace
-and (un)check the directories as required. To toggle this option on and off, click button 1 on
-.B import local namespace.
-These default directories are required by many commands for normal execution so it is recommended that they are not disabled unless they are definitely not needed. Importing a directory of the same name as one of the default directories will automatically overwrite the default. Therefore, it is not necessary to disable a default directory if the same name is to be imported from elsewhere.
-.PP
-A given directory can only be imported once so it is not possible, for example, to import
-.B /usr/inferno
-from two different machines.
-.I Session
-will automatically import the directories containing each of the selected commands but any others required must be explicitly imported. For example: If one of the commands is:
-.PP
-.EX
- /usr/inferno/runme.dis -f /appl/lib
-.EE
-.PP
-.I Session
-will import
-.B /usr/inferno/
-but
-.B /appl/lib
-would have to be specified in the namespace list.
-.SS Execution
-Once the command and namespace lists have been configured, click
-.B Ok
-on the
-.I Session
-window. This will bring up the
-.IR query (1)
-window containing a list of the available
-.IR cpu (4)
-resources. To select one or more of these for execution, click on the name with button 3 and it will be added to the list. If a specific
-.IR cpu (4)
-resource is not required, click button 3 on
-.B CPU resource
-and select the number you require by clicking on the number following the list entry and dragging the mouse up or down.
-.PP
-Once the required
-.IR cpu (4)
-resources have been selected, click
-.B Ok
-and execution will commence.
