* Program to take the place of the configure shell script under DOS.
* The makefile.in files are constructed in such a way that all this
* program needs to do is uncomment lines beginning ##DOS by removing the
* first 5 characters of the line. This will allow lines like:
* ##DOS!include windows.in to become: !include windows.in
*
* We also turn any line beginning with '@' into a blank line.
*
* If a config directory is specified, then the output will be start with
* config\pre.in, then the filtered stdin text, and will end with
* config\post.in.
*
* Syntax: wconfig [config_directory] <input_file >output_file
