# Basic Lines-Of-Code counter in Python source files, reporting the
# number of blank, comment and source code lines and total number of
# lines in all Python files scanned.
# Usage example:
# % python locs.py -rec ~/Projects
# 8691 *.py files: 365038 blank (14.0%), 212100 comment (8.1%),
# 2030198 source (77.9%), 2607336 total lines
# (2.739 secs, 951872 lines/sec)
# % python3 locs.py -rec ~/Projects
# 8691 *.py files: 365037 blank (14.0%), 212100 comment (8.1%),
# 2030198 source (77.9%), 2607335 total lines
# (2.599 secs, 1003158 lines/sec)
# % python3 locs.py -h
# usage: locs.py [-help] [-recurse] [-verbose] <file_or_dir_name> ...
# Tested with 64-bit Python 2.7.10 and 3.5.1 on MacOS 10.11.6 only.
