# haskell_count - count physical lines of code
# Strips out {- .. -} and -- comments and counts the rest.
# Pragmas, {-#...}, are counted as SLOC.
# BUG: Doesn't handle strings with embedded block comment markers gracefully.
# In practice, that shouldn't be a problem.
# Usage: haskell_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
# This is part of SLOCCount, a toolsuite that counts
# source lines of code (SLOC).
