     cobfusc --	make a C source	file unreadable	but compilable

     cobfusc [-AabdemntxV] [-c case] [-f suffix] [-g file] [-i idobf]
	     [-o file] [-p prefix] [-r file] [-s seed] [-u file] [-w cols]
	     [-z file] [file ...]

     This document contains only a brief description of	cobfusc.  For a	more
     complete documentation, please read the Info file or the Texinfo manual.

     The cobfusc utility converts the input file, written in the C language,
     into a human unreadable one, but compilable.  The main work is converting
     every identifier into a meaningless one, removing any comment and com-
     pacting all the white-spaces when they are	not required.

     The options are as	follows:

     -A	     Enable a heavy obfuscation	for the	source file.  This is equiva-
	     lent to the -ademt	-i numeric options.  The digraphize option is
	     not enabled by default since the Amendement 1 (1994) changes to
	     ANSI X3.159-1989 ("ANSI C89") are supported only by few C compil-

     -a	     Garble every string with octal escapes.

     -b	     Enable the	digraphize mode.

     -c	no | lower | upper | screw | random
	     Set the identifier	case obfuscation mode.

     -d	     Compact the macros	removing backslashes and white-spaces when
	     they are not required.

     -e	     Compact the white-spaces when they	are not	required.

     -f	suffix
	     Put the output of each processed file in a	separate file with
	     suffix appended to	file name instead of standard output.  This is
	     useful when processing a package with a lot of source files.

     -g	file
	     Add first the identifiers contained in file to the	obfuscation
	     table. Useful when	those identifiers are shared between two or
	     more source files.

     -i	no | numeric | word | random
	     Set the identifier	obfuscation mode.

     -m	     Strip the comments.

     -n	     Garble integers with expressions.

     -o	file
	     Set the output destination	to file.

     -p	prefix
	     Specify the prefix	to use when generating the identifiers.

     -r	file
	     Tell cobfusc that the identifiers contained in file must not be

     -s	seed
	     Specify the seed for generating the random	numbers.

     -t	     Enable the	trigraphize mode.

     -u	     Dump the symbol table to file.

     -V	     Print version information on standard output then exit.

     -w	     Set the width limit of the	output.

     -x	     Exclusive mode; obfuscate only the	identifiers specified by the
	     -g	and -z parameters.

     -z	file
	     Add the identifiers pairs contained in file to the	obfuscation

     cunloop(1), indent(1)
