The GNU 23# General Public License (GPL) does govern all other use of the material 24# that constitutes the mkerrcodes.awk program. 25# 26# Certain portions of the mkerrcodes.awk source text are designed to be 27# copied (in certain cases, depending on the input) into the output of 28# mkerrcodes.awk.

(In other words, 40# unless your change moves or copies text from the non-data portions to the 41# data portions.) If your modification has such potential, you must delete 42# any notice of this special exception to the GPL from your modified version. 43 44# The input file is in the following format: 45# [CODE SYMBOL...] 46# @errnos@ 47# [CODE SYMBOL...] 48# 49# The difference between the sections is how symbol is transformed. 50# The second section gets GPG_ERR_ prepended before processing. 51# 52# Comments (starting with # and ending at the end of the line) are removed, 53# as is trailing whitespace. 54 55BEGIN { 56 FS="[ \t]+"; 57 print ";;;; Output of mkerrcodes.awk.
