Wonder if this will break it on all other platforms :-)

to specify where it should go (if specified, even local files will be
copied into the given file).

Note that .pyc files are platform independent.

- Support ~[user] expansion.

- Remember last directory and pattern; optional 'key' argument
specifies different memory locations.

- Absolutify pathnames if possible.

- WM close event cancels the dialog.

- First arg to go() can be either a directory or a file (renamed to
dir_of_file); defaults to current directory.

Change RHooks() interface to not require a 'rexec' instance argument;
added set_rexec() method instead (which must be called by the RExec
instance using this RHooks instance).

Support dynamic loading of modules, at least for those modules that
are ok built-in modules.  Added new interfaces set_trusted_path() and
load_dynamic() to RExec class (the default trusted path consists of
all absolute pathnames in sys.path).

Change copy_except() to actually try to delete the exceptions.

Split the AC_CHECK_FUNCS() line using backslashes.
Added FreeBSD support.
Added XXX comment -- need to be more liberal or careful about -lreadline.
