2.2 Command Line Arguments

empty, in which case the option string is not changed.

Because FunnelWeb processes its command line arguments from left to right, a

later argument can cancel the effect of an earlier one. For example fw +t  t will

result in the t option ending up 

off

 . This allows users to set up their own default

arguments by defining a symbol in their operating system s command language.

For example, a Unix user who wants FunnelWeb to delete all identical output

files and create a documentation file on each run with a default .typ extension

could simply place the following definition in their "

.login

" file.

alias fw fw +d +t.typ

These default options can then later be easily overridden on the command line.
