+\footnote{$^4$}{This extended version of \.{CWEB} adds the following options

+\option i Indent parameters in function declarations.  This causes the
+formal parameter declarations in function heads to be indented.  (On by
+default; \.{-i} typesets declarations flush left; some people think this
+to be more logical than indenting them) (Has no effect on \.{CTANGLE}.)
+
+\option l This option takes the string of characters to its right as its
+argument to switch between different user languages and macro packages.
+For example, if you call \.{CWEAVE} with the `\.{+ld}' (or `\.{-ld}') option,
+the German \.{CWEB} macros \.{dcwebmac.tex} will be loaded in the first line
+of output instead of the English ones. To avoid conflicts, the Danish
+macros could be called \.{dkcwebmac.tex} and would be included by `\.{+ldk}'.
+(Off by default) (Has no effect on \.{CTANGLE}.)
+
+\option o Separate declarations and the first statement in a function block.
+\.{CWEAVE} automatically inserts a bit of extra space.  (On by default.)
+(Has no effect on \.{CTANGLE}.)

+\option t Overwrite output files with temporary output only if changes occur.
