#!/usr/bin/perl
# perl_count - count physical lines of code in Perl programs.
# Usage: perl_count [-f file] [list_of_files]
#  file: file with a list of files to count (if "-", read list from stdin)
#  list_of_files: list of files to count
#  -f file or list_of_files can be used, or both

# Physical lines of Perl are MUCH HARDER to count than you'd think.
# Comments begin with "#".
# Also, anything in a "perlpod" is a comment.
# See perlpod(1) for more info; a perlpod starts with
# \s*=command, can have more commands, and ends with \s*=cut.
# Note that = followed by space is NOT a perlpod.
# Although we ignore everything after __END__ in a file,
# we will count everything after __DATA__; there's arguments for counting
# and for not counting __DATA__.

# What's worse, "here" documents must be COUNTED AS CODE, even if
# they're FORMATTED AS A PERLPOD.  Surely no one would do this, right?
# Sigh... it can happen. See perl5.005_03/pod/splitpod.

# This is part of SLOCCount, a toolsuite that counts
# source lines of code (SLOC).
