                      7: .SH DESCRIPTION
                      8: \fICppp\fR filters standard input to standard output, processing the
                      9: C preprocessor control lines \*M#ifdef\fR,
                     10: \*M#ifndef\fR, and \*M#else\fR. If the controlling identifier is
                     11: in the arguments following the \f3\-d\fR option, the corresponding
                     12: lines are included, while if the controlling identifier is in the
                     13: arguments following the \f3\-u\fR option, the corresponding lines
                     14: are deleted. Otherwise, the preprocessor control lines are included.
                     15: The control lines \*M#define\fR and \*M#undef\fR are deleted if
                     16: the identifier is in either list.
                     17: .PP
                     18: For example, suppose that a program contains code for 8-bit, 16-bit, and 32-bit processors
                     19: under control of the identifiers \*MBIT8\fR, \*MBIT16\fR, and \*MBITB2\fR.
                     20: A version
                     21: of the program for 16-bit processors only can be obtained by
                     22: .DS
