1) on the issue on what does the c= ommand do=2C I think that this issue was closed by the dicussion: "dir" is = a file that is at the same level as the info file to add. This is the norma= l way to make info files appear in Emacs info menu.

2) On the issue= of supporting older versions of Window: I am afraid that this is not possi= ble if you want a DOS command. I don't think that there is any simple way t= o extract the dirname with a one-liner command in older DOS versions.

In that = case it will work only if the info file is at the root of the current Dired= buffer.

I am not sure how to disntiguish Windows version from withi= n Emacs.

Given that installation of info files is not that current=2C I think th= at the first alternative is simpler (ie omit the directory name for older v= ersion of DOS=2C and let the user care about it).

>=3B Thanks. However=2C the command you su= ggest for windows-nt will only

>=3B Emacs still supports older Wind= ows versions where the shell is

>=3B
>=3B So an alternative for older shells will b= e needed before this can go
