A string input, "-s" should be used whenever an ASCII string
is needed as an input parameter.
Comment text is just used to put additional information on the pane
to aid the user in understanding what to do and does not
affect the command line user interface.
.PP
To add a new string item in your pane, click on
the "STRING VALUE" button.
This will pop-up a list of the -s template item
that you can add.  Click on the item in the list that you want.
Once you have done this, you can begin editing the fields in the
bottom two thirds of the composer form.
.PP
If you have an existing -s item, and wish to add
another, you have the option of copying an existing item or adding
a new one.  To add a new item, just click on the 
"STRING VALUE" button.  The list that pops up will have
a new template item as the last entry on the list.  
.PP
If you wish to
copy an existing item, click on the "COPY" button.  This will give you a list
of all items on the pane that you are editing.  Select the -s
line in the list that you wish to copy.  A new line will be created with
a position that is below the selected item.
.PP
After a -s line is selected, edit the fields in the composer form
to meet your requirements.  The fields both determine the appearance of
the graphical user interface (the pane) and the command line user
interface.  Though you can immediately view the pane, ghostwriter must
be run before you can examine the command line user interface.
.PP
There are several conventions to follow for the string input parameters.  
They should be positioned below any input/output files in the
pane that you are editing.
The variable or command line argument flag should usually
be as short as possible, single characters are preferred.

The "Live" option field should not be used for cantata pane files.
