Denny - -# The arguments to this script should be names of files that contain -# copyright statements to be updated. The copyright holder's name -# defaults to "Free Software Foundation, Inc." but may be changed to -# any other name by using the "UPDATE_COPYRIGHT_HOLDER" environment -# variable. -# -# For example, you might wish to use the update-copyright target rule -# in maint.mk from gnulib's maintainer-makefile module. -# -# Iff a copyright statement is recognized in a file and the final -# year is not the current year, then the statement is updated for the -# new year and it is reformatted to: -# -# 1. Fit within 72 columns. -# 2. Convert 2-digit years to 4-digit years by prepending "19". -# 3. Expand copyright year intervals. (See "Environment variables" -# below.) -# -# A warning is printed for every file for which no copyright -# statement is recognized. -# -# Each file's copyright statement must be formatted correctly in -# order to be recognized. For example, each of these is fine: -# -# Copyright @copyright{} 1990-2005, 2007-2009 Free Software -# Foundation, Inc. -# -# # Copyright (C) 1990-2005, 2007-2009 Free Software -# # Foundation, Inc. -# -# /* -# * Copyright © 90,2005,2007-2009 -# * Free Software Foundation, Inc. -# */ -# -# However, the following format is not recognized because the line -# prefix changes after the first line: -# -# ## Copyright (C) 1990-2005, 2007-2009 Free Software -# # Foundation, Inc. -# -# However, any correctly formatted copyright statement following -# a non-matching copyright statements would be recognized. -# -# The exact conditions that a file's copyright statement must meet -# to be recognized are: -# -# 1. It is the first copyright statement that meets all of the -# following conditions. Subsequent copyright statements are -# ignored. -# 2. Its format is "Copyright (C)", then a list of copyright years, -# and then the name of the copyright holder. -# 3. The "(C)" takes one of the following forms or is omitted -# entirely: -# -# A. (C) -# B. (c) -# C. @copyright{} -# D. © -# -# 4. The "Copyright" appears at the beginning of a line, except that it -# may be prefixed by any sequence (e.g., a comment) of no more than -# 5 characters -- including white space. -# 5. Iff such a prefix is present, the same prefix appears at the -# beginning of each remaining line within the FSF copyright -# statement. There is one exception in order to support C-style -# comments: if the first line's prefix contains nothing but -# whitespace surrounding a "/*", then the prefix for all subsequent -# lines is the same as the first line's prefix except with each of -# "/" and possibly "*" replaced by a " ". The replacement of "*" -# by " " is consistent throughout all subsequent lines. -# 6. Blank lines, even if preceded by the prefix, do not appear -# within the FSF copyright statement. -# 7. Each copyright year is 2 or 4 digits, and years are separated by -# commas or dashes. Whitespace may appear after commas. -# -# Environment variables: -# -# 1. If UPDATE_COPYRIGHT_FORCE=1, a recognized FSF copyright statement -# is reformatted even if it does not need updating for the new -# year. If unset or set to 0, only updated FSF copyright -# statements are reformatted. -# 2. If UPDATE_COPYRIGHT_USE_INTERVALS=1, every series of consecutive -# copyright years (such as 90, 1991, 1992-2007, 2008) in a -# reformatted FSF copyright statement is collapsed to a single -# interval (such as 1990-2008). If unset or set to 0, all existing -# copyright year intervals in a reformatted FSF copyright statement -# are expanded instead. -# If UPDATE_COPYRIGHT_USE_INTERVALS=2, convert a sequence with gaps -# to the minimal containing range. For example, convert -# 2000, 2004-2007, 2009 to 2000-2009. -# 3. For testing purposes, you can set the assumed current year in -# UPDATE_COPYRIGHT_YEAR. -# 4. The default maximum line length for a copyright line is 72. -# Set UPDATE_COPYRIGHT_MAX_LINE_LENGTH to use a different length. -# 5.
