I use GNU gawk on win32 platforms and standard cmd.exe to run cmd files containing gawk commands. If I were in a unix shell I would use igawk to process "@includes" for awk "libraries" and convert them into a gawk cmd. I know you can use cygwin bash to run igawk in win32 platforms.
I was just wondering if anyone has seen igawk shell script translated into a similar windows cmd file that would process "@includes". Just a thought
