complexity (GNU Complexity) - Measure complexity of C source - Ver. 0.4
USAGE: complexity [ -<flag> [<val>] | --<name>[{=| }<val>] ]... \
 [ <file-name> ... ]
 -t, --threshold=num Reporting threshold
 --horrid-threshold=num zero exit threshold
 -n, --nesting-penalty=str score multiplier for nested code
 --demi-nesting-penalty=str score multiplier for nested expressions
 -s, --scale=num complexity scaling factor
 -h, --histogram Display histogram of complexity numbers
 - disabled as --no-histogram
 - may not be preset
 -c, --scores Display the score for each procedure
 - disabled as --no-scores
 - may not be preset
 -I, --ignore=str procedure name to be ignored
 - may appear multiple times
 -H, --no-header do not print scoring header
 - may not be preset
 -u, --unifdef=str Run the source(s) through unifdef(1BSD)
 - may appear multiple times
 --unif-exe=str Specify the unifdef program
 -i, --input=str file of file list
 --trace=str trace output file
 -v, --version[=arg] Output version information and exit
 -?, --help Display extended usage information and exit
 ->, --save-opts[=arg] Save the option state to a config file
 -<, --load-opts=str Load options from a config file
 - disabled as --no-load-opts
 - may appear multiple times
Options are specified by doubled hyphens and their name or by a single
hyphen and the flag character.
Compute the complexity of source code not just with a
path-through-the-code count, but also amplifying line counts by logic
level nesting.
If no arguments are provided, input arguments are read from stdin,
one per line; blank and '#'-prefixed lines are comments.
'stdin' may not be a terminal (tty).
The following option preset mechanisms are supported:
 - reading file $@/complex.conf
 - reading file $HOME/.complexityrc
 - reading file $PROJECT_ROOT/complex.conf
 - reading file ./.complexityrc
 - examining environment variables named COMPLEXITY_*
``complexity'' ignores all cpp preprocessor directives - calculating
the complexity of the appearance of the code, rather than the complexity
after the preprocessor manipulates the code. ``getchar(3)'', for example,
will expand into quite complicated code.
