+
+# This script checks whether the files in the GNU gettext package
+# have the required copyright headers resp. license notices.
+#
+# Copyright notices have two purposes:
+#
+# 1. They tell the people who obtain the package (as a git checkout,
+# source tarball, or binary package) what they are allowed to do
+# with it.
+#
+# 2. They provide the legal basis for suing people who infringe on
+# the copyright of the package (or part of it). In particular,
+# they should prove that the infringer knew what they were doing
+# when they took a source file (or part of it) and used it in
+# a way that is not compliant with the license.
+#
+# For the purpose 1, a file COPYING at the top-level of the package
+# and a reference to it in the main README are all that's needed.
+#
+# For the purpose 2, we put copyright notices in each file that we
+# don't want to be abused of. See also the section "Copyright Notices"
+# in the 'Information for maintainers of GNU software',
+# <https://www.gnu.org/prep/maintain/html_node/Copyright-Notices.html>.
+#
+# This script helps with purpose 2. The input of this script is a
+# source tarball, not a git checkout. Rationale:
+# - It is convenient to add files to a git repository, without having
+# to attach a copyright notice to it.
+# - Files that we don't include in the source tarball are not so valuable
+# that we would like to sue infringers over them.
+#
+# We classify the files in several categories:
+# - Source code that ends up being executed by end users (in source or
+# compiled form). This is the most valuable one and needs copyright
+# notices.
+# - Source of large documentation. This is valuable too, and needs
+# copyright notices.
+# - Source code of build infrastructure.
+# - Files that contain convenience information for programmers and
+# packagers.
+# The latter categories are not valuable enough to warrant sueing
+# infringers.
+#
+# Not all files files qualify for a copyright header. Namely, since
+# copyright applies to the expression of an idea (think roughly of the
+# program as an art work), it makes no sense to attach a copyright header
+# to a file which different programmers would write in the same way.
+# This includes tiny files, as well as files that contain only machine-
+# generated data.
