The field delimiter tells veefu how
to parse each line.  White Space
will separate each line into fields
between each block of spaces
and tabs.  Tab will generate fields
for
each tab and custom will
allow any sequence of characters
to act as a delimiter.  This also
sets the output delimiter for every
tool except the Columns tool.
Pipe To tells where the incoming pipe's text should
be piped.  Standard Input simply passes the text to
the tool; Parameters allows you to use the previous
tools outgoing text in the parameter fields by using
the '&' sign and the ordinal value of the text; File List
uses the incoming lines as filenames.
Add File brings up a file selector dialog
to add a new file to the list, inserting it
at the currently selected position.  
Remove removes all selected files and
there is always at least one file
selected.  Use the keyword 'stdin' in
the file list to treat incoming text as
though it were a file.
Sideways arranges the file
text in Columns instead of
the default behaviour which
concatenates them.  The
Field Delimiter described
above separates columns
between files.
The Tool Chain lists the order in which the tools in the script will
execute.  In this example the Body Tool's pushed state indicates that it
is the currently active tool.  
Incoming text from the
previous tool
Text that has been processed,
going out to the next tool.
Pressing the red
run icon will run
the script from
the beginning to
the active tool.
The Yellow run button will run only the
selected tool, useful for testing a
change in parameters.
