\fBscc\fP [-chnwCV][-s rep][-q rep] [file ...]

.SH DESCRIPTION
1010
The \fBscc\fP program strips C comments from source code.
11-
By default, it only eliminates classic C comments between `\*c/*\*d' and `\*c*/\*d'.
12-
By specifying `\*c-C\*d', you can also eliminate C++ and C99 comments between `\*c//\*d' and end of line.
13-
By specifying `\*c-w\*d', you can obtain warnings about nested C comments - that is, about `\*c/*\*d' appearing inside another classic C comment.
11+
By default, it eliminates both classic C comments between `\*c/*\*d' and
12+
`\*c*/\*d' and C++ and C99 comments between `\*c//\*d' and end of line.
13+
By specifying `\*c-C\*d', you can arrange to eliminate only classic C
14+
comments.
15+
By specifying `\*c-w\*d', you can obtain warnings about nested C
16+
comments - that is, about `\*c/*\*d' appearing inside another classic C
17+
comment.
18+
The `\*c-c\*d' option prints comments and not the code.
19+
The `\*c-n\*d' option keeps newlines in comments, so the input and
20+
output line counts should be the same, even though comments were
21+
stripped.
22+
.P
23+
The `\*c-s rep\*d' option replaces the body of string literals with the
24+
single character specified by `\*crep\*d', which can simplify some forms
25+
of analysis.
26+
Similarly, the `\*d-q rep\*d' option replaces the body of character
27+
literals with the single character specified by `\*crep\*d'.
28+
.P
1429
The `\*c-V\*d' option prints the version information and exits.
30+
The `\*c-h\*d' option prints a help message and exits.

.SH BUGS
45+
Earlier versions of \fBscc\fP used `\*c-C\*d' to enable the removal of
46+
C99 or C++ comments.
47+
The behaviour was reversed in version 5.3.
