`pwd': Print working directory
==============================

   `pwd' prints the fully resolved name of the current directory.  That
is, all components of the printed name will be actual directory
names--none will be symbolic links.

   Because most shells have a built-in command by the same name, using
the unadorned command name in a script or interactively may get you
different functionality than that described here.

   The only options are a lone `--help' or `--version'.

`--help'
     Print a usage message listing all available options, then exit
     successfully.

`--version'
     Print the version number, then exit successfully.
