File staging allows you to specify which (if any) files to copy onto the
execution host before the job starts, and which (if any) to copy off when
the job completes.  

PBS staging works like this: "move file X from HERE to THERE". Both HERE
and THERE can be relative or absolute.

The File Staging dialog box is composed of 3 regions:

(1) File Selection Box region
(2) Stagein/Stageout region
(3) Command Buttons

==================
File Selection Box 
==================
This is originally "iconized" in the form of a button labeled "Click me to
bring up File Selection Box..". Upon clicking this button, the file selection
box will be displayed to allow the selection of a single file from the
the directory tree path of the local host. This single file can be used as 
input to HERE host/input_file in Stagein, and HERE host/output_file in
Stageout of files. The listing directory is specified in
SELECTION DIRECTORY entrybox, and the name of the local host is given in HOST.
The accompanying listbox shows the list of files/directories in the "SELECTION
DIRECTORY".

Single clicking a file will display the filename on the "FILE Selected" entry
box.
Double clicking on a directory will refresh the display of the listbox to show
the files in the selected directory.

You can also manually entry the name of the directory on the
"SELECTION DIRECTORY" entrybox, hit <RETURN>, and then the files in that
directory will be listed. You can also manually enter the filename of your
choice on the "FILE Selected" entrybox.

To remove the "File Selection Box" from view, click on "Click me to remove
File Selection Box".

=======================
Stagein/Stageout region
=======================
The Stagein/Stageout region contains 2 box widgets for specifying
the stagein and stageout attribute values of the job. These attributes
represent what files are staged (copied) in before job start, or staged out
after job completes execution.

Type in the values for stagein hostname, input file, and local file, and the
stageout hostname, output file, local file in the provided input entry widgets.
That is, on each entry, specify the "input file" ("host" specifies its
location) that will be copied to the execution host as "local file" before job
execution starts. Similarly, specify the "local file" on the execution host
that will be copied back to "host" as "output file" when job execution
finishes. Or, click on the accompanying button "Add file selected from File
Selection Box" to load the selected file into the input entries. After you've
entered the values, then click the accompanying "add" buttons.  Watch as your
input gets loaded into the "Stagein_Files:" and "Stageout_Files:" listboxes.
Entries of the latter can be deleted by selecting an entry, and then clicking
the accompanying "delete" button. If you want to modify an entry in a listbox,
then select the entry via mouse, which would result in its values to be loaded
into the input entries, then change the values of the input entries, and then
click the accompanying "update" button. 

You can move through the input entry fields using <Tab>, <Cntrl-f>, or
<Cntrl-b> (to go backwards). A horizontal scrollbar is associated with each
field to scan horizontally a long input string.  Within an entry field, you can
use the left and right arrow keys, backspace or delete key, and mouse to
highlight/select a text for immediate overwriting of newly typed character.

================
Command Buttons
================
Click on "ok" button after you are satisfied with the stagein/stageout 
attribute values set for the job.

Click on "reset to default" if you want to reset the stagein/stageout attribute
values to the default settings.
