Report on style conformance for one or more C source or header files.

Input is either from a list of files supplied as command line parameters,
or as a list of newline separated file names read from standard input.
Reports are:
--summary A one line per file report of the file name, number of lines, number of non-compliant lines, and a score.
--average A single line output of the average of all scores.
--total A single line of output of the percentage of all compliant lines to the total number of lines in all files.
--visual A visual representation of the style check.

For each of these reports, the output format is specified by:
--output text  Display text on standard output
--output csv Display a list of comma-separated values on standard output.
--output gui Use a graphical user interface if possible.

The visual report displays either a colorized, line by line output of
the differences between the original source file it's exemplar (-o text),
or displays a file-merge application for interactive use ()-o gui)

Example:

% longbow-style-report *.[ch]

Report conformance of the .c and .h files specified as command line parameters.

% longbow-style-report -
Report conformance of the .c and .h files read from standard input, one line per file.

$ longbow-style-report parc_JSON.c
parc_JSON.c   239     0 100.00$
$
$ echo parc_JSON.c | longbow-style-report -
parc_JSON.c,239,0,100.00
