# Certain portions of the mkerrcodes.awk source text are designed to be
# copied (in certain cases, depending on the input) into the output of
# mkerrcodes.awk. We call these the "data" portions. The rest of the
# mkerrcodes.awk source text consists of comments plus executable code

# We call these comments and executable code the "non-data" portions.
# mkerrcodes.awk never copies any of the non-data portions into its output.

# This special exception to the GPL applies to versions of mkerrcodes.awk
# released by g10 Code GmbH. When you make and distribute a modified version

# 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.
# The input file is in the following format:
# [CODE SYMBOL...]
# @errnos@
# [CODE SYMBOL...]
#
# The difference between the sections is how symbol is transformed.
# The second section gets GPG_ERR_ prepended before processing.
#
# Comments (starting with # and ending at the end of the line) are removed,
# as is trailing whitespace.
