# Certain portions of the mkerrcodes.awk source text are designed to be

# mkerrcodes.awk. We call these the "data" portions. The rest of the
# mkerrcodes.awk source text consists of comments plus executable code

# This special exception to the GPL applies to versions of mkerrcodes.awk

# apply to your modified version as well, *unless* your modified version
# has the potential to copy into its output some of the text that was the
# non-data portion of the version that you started with. (In other words,
# unless your change moves or copies text from the non-data portions to the
# data portions.) If your modification has such potential, you must delete
# any notice of this special exception to the GPL from your modified version.
# This script outputs an intermediate file that contains the following output:
# static struct
# {
# int err;
# const char *err_sym;
# } err_table[] =
# {
# { 7, "GPG_ERR_E2BIG" },
# [...]
# };
#
# The input file is a list of possible system errors, followed by a GPG_ERR_* name:
#
# 7 GPG_ERR_E2BIG
#
# Comments (starting with # and ending at the end of the line) are removed,
# as is trailing whitespace.
