+#!/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).
