The chilight utility colorizes the input file, expected to be written in the C language, with text
attributes or markups.
The options are as follows:
-fformat
Set the output format to format.
The format can be one of: ansi_color, ansi_bold, html_color, html_font, roff or tty (the
default).
-ofile
Set the output destination to file.
-ttitle
Specify the page title for the generated HTML page.
-V Print version information on standard output then exit.
-wwidth
Set the tab width for the roff style.
Tabulator characters are converted to suitable amounts of space characters to gain better
typographic quality on roff output. Acceptable values are in the range 1..16 which should be
ample for most situations.
