[PATCH] pcmcia: expose tool in pcmcia/Documentation/pcmcia/
Expose example and tool source files in the Documentation/ directory in their own files instead of being buried (almost hidden) in readme/txt files. This will make them more visible/usable to users who may need to use them, to developers who may need to test with them, and to janitors who would update them if they were more visible. Also, if any of these possibly should not be in the kernel tree at all, it will be clearer that they are here and we can discuss if they should be removed.

The hex value after "pa" is the hash of product ID string 1, after "pb" for
string 2 and so on.
