# fortran_count - count physical lines of code in Fortran 77.
# Usage: fortran_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
# Ignores comment-only lines
# (where column 1 character = C, c, *, or !,
# or where a ! is preceded only by white space)
# Lines beginning with !hpf$ or !omp$ are not comments lines either.
# This is part of SLOCCount, a toolsuite that counts
# source lines of code (SLOC).
