+.SH DESCRIPTION
+.PP
+This program is part of
+.BR "Netpbm" (1)\c
+\&.
+.PP
+This program makes colors legal in the NTSC (or PAL) color systems.
+Often, images generated on the computer are made for use in movies
+which ultimately end up on a television screen.  However, the range of colors
+(as specified by their RGB values) on a computer does not match the
+range of colors that can be represented using the NTSC (or PAL)
+systems.  If an image with "illegal" colors is sent directly
+to an NTSC (or PAL) video system for recording, the
+"illegal" colors will be clipped.  This may result in an
+undesirable looking picture.
+.PP
+This utility tests each pixel in an image to see if it falls
+within the legal NTSC (or PAL) range.  If not, it raises or lowers the
+pixel's saturation in the output so that it does fall within legal
+limits.  Pixels that are already OK just go unmodified into the
+output.
+.PP
+Input is from the file named \fIinput\fP.  If \fIinput\fP is
+\fB-\fP, input is from Standard Input.  If you don't specify
+\fIinput\fP, input is from Standard Input.
+.PP
+Output is always to Standard Output.
+.PP
+This program handles multi-image PPM input, producing multi-image
+PPM output.
+
+.UN options
+.SH OPTIONS
+.PP
+In addition to the options common to all programs based on libnetpbm
+(most notably \fB-quiet\fP, see 
+.UR index.html#commonoptions
+ Common Options
+.UE
+\&), \fBppmntsc\fP recognizes the following
+command line options:
+
+
+
+.TP
+\fB--pal\fP
+Use the PAL transform instead of the default NTSC.
+
+.TP
+\fB--verbose\fP
+Print a grand total of the number of illegal pixels.
+
+.TP
+\fB--debug\fP
+Produce a humongous listing of illegal colors and their legal counterparts.
+NOTE:  This option may produce a great deal of output.
+
+.TP
+\fB--legalonly\fP
+Output only pixels that are already legal.  Output black in place of pixels
+that are not.
+
+.TP
+\fB--illegalonly\fP
+Output only pixels that are illegal (and output them uncorrected).
+Output black in place of pixels that are already legal.
+
+.TP
+\fB--correctedonly\fP
+Output only pixels that are corrected versions of illegal pixels.  Output
+black in place of pixels that are already legal.
