+.SH USAGE
 .PP
 The command line should have one, two, or three names on it.
-The first is taken as the CWEB file (and
-.B .w
-is added if there is no extension).
-If that file cannot be opened, the extension
-.B .web
-is tried instead. (But
-.B .w
-is recommended, since
-.B .web
-usually implies Pascal.)
-If there is a second name, it is a change file (and
-.B .ch
-is added if there is no extension).
-The change file overrides parts of the WEB file,
-as described in the documentation.
-If there is a third name, it overrides
-the default name of the output file, which is ordinarily the same as
-the name of the input file (but on the current directory) with the
-extension
-.B .c
-or
-.BR .tex .
-.PP
-Options in the command line may be either turned off with\ '\-'
-(if they are on by default) or turned on with\ '+' (if they are off by
-default).
-In fact, the options are processed from left to right,
-so a sequence like '-f\ +f' corresponds to '+f' (which is the default).
-.PP
-Both programs operate silently by default (as of 2019).
-.PP
-The
-.B +b
-option prints the banner line on your terminal
-when ctangle or cweave begins.
-The
-.B +h
-option prints the happy message if the processing
-was successful.
-The
-.B +p
-option prints progress reports (starred module numbers) as the processing
-takes place.
-.PP
-The
-.B +s
-option prints statistics about memory usage at the end of a run.
-.PP
-There are six other options applicable to
-.B cweave
-only:
-.B \-e
-inhibits the enclosure of C\ material formatted by
-.B cweave
-in
-\ePB{.\|.\|.}
-brackets.
-Such brackets are normally inserted so that special hooks
-can be used by
-.I cweb-latex
-and similar programs.
-By default,
-\ePB{.\|.\|.}.
-is defined as a no-op.
-.B \-f
-means do not force a newline after every statement in the formatted output.
-.B \-i
-suppresses the indentation of parameter declarations.
-.B \-lX
-(or +lX) uses macros for language X\ from Xcwebmac.tex.
-.B \-o
-suppresses the visual separation of declarations and statements.
-.B \-x
-means omit the index and table of contents.
-.\"=====================================================================
+The first is taken as the CWEB input file (and \f[B].w\f[R] is added if
+there is no extension).
+If there is a second name, it is a change file (and \f[B].ch\f[R] is
+added if there is no extension).
+The change file overrides parts of the CWEB file, as described in the
+documentation.
+If there is a third name, it overrides the default name of the output
+file, which is ordinarily the same as the name of the input file (but on
+the current directory) with the extension \f[B].tex\f[R].
+If you just want to change the output file name, but don\[cq]t have a
+change file to apply, you can use `\f[B]\-\f[R]' as the second argument.

 2019-01-26  Luigi Scarso  <luigi.scarso@gmail.com>
 	* Fixed bisection algorithm (overflow of number of bisections in decimal mode with  low precision)
 	* Added 2 levels to the bisection algorithm for cubic intersection. Need testing.
