Force. \fBtex2lyx\fR will not run if the .lyx file it would generate already exists.
Use the \fB\-f\fR option (carefully) to clobber any existing files.
.TP

-Help. Print out usage information and quit.
-.TP
.BI \-n
Noweb. Translate a noweb (aka literate programming) file. This should be
(almost?) equivalent to running \*(L"noweb2lyx foo.tex foo.lyx\*(R". This option
requires the \fB\-c\fR option.
-.TP
-.BI \-p
-Partial file. The input files are LaTeX fragments, with no preamble matter or
-\f(CW\ebegin{document}\fR commands. This option requires the \fB\-c\fR option, since there
-are no \f(CW\edocumentclass\fR commands in the files \fBtex2lyx\fR is translating. When
-using this option, you can translate more than one file, as long as all files
-are the same class. The LyX file created by \fBtex2lyx\fR can be included in an
-existing LyX file using the \*(L"Include LyX File\*(R" command from
-LyX's Insert menu. (\fBNOTE\fR: this feature of the older \fBreLyX\fR script has
-not yet been implemented in \fBtex2lyx\fR).
-.TP
-.BI \-r
-Regular environments (see the section on \fISyntax Files\fR). If you give more than one
-environment, separate them with commas (not spaces). You'll probably need to
-quote the environment list, especially if it has asterisk environments (foo*)
-in it. If you use this command often, considering creating a personal syntax
-file. (\fBNOTE\fR: this feature of the older \fBreLyX\fR script has
