DESCRIPTION

34       countperl uses Perl::Metrics::Simple to examines the named files and
35       recursivesly searches named directories for Perl files.
36
37       Perl files are identified by Perl::Metrics::Simple->is_perl_file.
38       Basically if the file ends in ".pl", ".pm", or ".t" or has what appears
39       to be a perl shebang line.
40
41       countperl produces a report on STDOUT of counts of total lines,
42       packages, subroutines/methods, the minimum, maximum, mean, standard
43       deviation, and median size and mccabe_complexity (cyclomatic
44       complexity) of subroutines and the 'main' portion of each file
45       (everything not in a subroutine.)
46
47   Output Format
48       Line counts do not include comments nor pod.
49
50       The current output format is human-readable text:
