  Hello,

======================================================================
octave:3> help path
path is the user-defined function from the file
/usr/local/share/octave/2.1.50/m/miscellaneous/path.m
 
 - Function File:  path (...)
     Modify or display Octave's `LOADPATH'.
 
     If NARGIN and NARGOUT are zero, display the elements of Octave's
     `LOADPATH' in an easy to read format.
 
     If NARGIN is zero and nargout is greater than zero, return the
     current value of `LOADPATH'.
 
     If NARGIN is greater than zero, concatenate the arguments,
     separating them with `":"'.  Set `LOADPATH' to the result and also
     return it.
 
     No checks are made for duplicate elements.
======================================================================

  With octave-forge, you also get addpath(), rmpath() :


======================================================================
octave:4> help addpath
addpath is the user-defined function from the file
/home/etienne/prog/octave/octave-forge/octave-forge/main/path/addpath.m
 
      addpath(dir1,...)
 
Prepends dir1,... to the current LOADPATH.
 
      addpath(dir1,'-end',dir2,'-begin',dir3,'-END',dir4,'-BEGIN',dir5)
 
Prepends dir1, dir3 and dir5 and appends dir2 and dir4.
 
For m****b compat.
 
BUG : Can't add directories called '-END', '-end', '-BEGIN' or '-begin'
      Can't add directories that are not readable by their owner
 
FEATURE : Won't add a string that is not a dir.
 
octave:5> help rmpath
rmpath is the user-defined function from the file
/home/etienne/prog/octave/octave-forge/octave-forge/main/path/rmpath.m
 
      rmpath(dir1,...)
 
Removes dir1,... from the current LOADPATH.
 
For m****b compat.
======================================================================

  Hth,

  Etienne
