# Morgan Deters <mdeters@cs.nyu.edu> for CVC4
# Copyright (c) 2009, 2010 The CVC4 Project
#
# usage: update-copyright [ files/directories... ]
#
# This script goes through a source directory rewriting the top bits of
# source files to match a template (inline, below). For files with no
# top comment, it adds a fresh one.
#
# usage: contrib/update-copyright.pl [dirs...]
# if dirs... are unspecified, the script scans its own parent directory's
# "src" directory. Since it lives in contrib/ in the CVC4 source tree,
# that means src/ in the CVC4 source tree.
#
# It ignores any file/directory not starting with [a-zA-Z]
# (so, this includes . and .., vi swaps, .svn meta-info,
# .deps, etc.)
#
# It ignores any file not ending with one of:
# .c .cc .cpp .C .h .hh .hpp .H .y .yy .ypp .Y .l .ll .lpp .L .g
# (so, this includes emacs ~-backups, CVS detritus, etc.)
#
# It ignores any directory matching $excluded_directories
# (so, you should add here any sources imported but not covered under
# the license.)
my $excluded_directories = '^(minisat|CVS|generated)$';
my $excluded_paths = '^(src/parser/bounded_token_buffer\.(h|cpp))|(src/parser/antlr_input_imports.cpp)$';
# Years of copyright for the template. E.g., the string
# "1985, 1987, 1992, 1997, 2008" or "2006-2009" or whatever.

Warning: this script is dangerous. It will overwrite the header comments in your
source files to match the template in the script, attempting to retain file-specific
comments, but this isn't guaranteed. You should run this in an svn working directory
and run "svn diff" after to ensure everything was correctly rewritten.
