userpath function implemented - need testers

[TrucomanX XnamocurT]

Hi
I have implemented

the function userpath() of matlab:

  myuserpath=userpath('reset')
  userpath('/home/username/mystartupdir')
  userpath('reset')
  userpath('clear')

And others interesting (I think so) multiplatform functions as:

% Home user directory, like OCTAVE_HOME()

USER_HOME()

ans=\home\user

and=C:/Users/user

%If exist some_directory directory in the path()

existpath(some_directory)

ans=1

ans=0

% similar a userpath but return a directory not a path

  USERDIR=USER_DIR()
  USERDIR=USER_DIR('default')
  USERDIR=USER_DIR('loaddefault')
  USERDIR=USER_DIR('loadlast')
  USERDIR=USER_DIR('/home/username/mystartupdir')
  USERDIR=USER_DIR('clear')

And I propose a modification  at the end the .octaverc file for it to work userpath and USER_DIR

% .octaverc
if (exist(USER_DIR('loadlast'),'dir')==7)

    disp(['Loaded last startup user directory: ',USER_DIR()]);

end

the files can be download from:

I also like information over how submit this modifications.

thanks
