-## FIXME: this file is here to avoid conflicts with new Octave versions. Matlab
-##        has recently added strplit function (used to exist in Octave only) but
-##        their syntax is not compatible with ours. Rather than timing the
-##        release of each octave forge package that used strsplit, a copy of the
-##        old version was placed as private. Once the new Octave version is
-##        released, this file can be removed, and the calls to strsplit fixed.
+% parts = strsplit(name,sep);
+%
+% A simple strsplit implementation.
+%
+% Once a strsplit becomes widespread in octave and Matlab,
+% this file can be deleted.
+%
+% This file is preferred over octave's strsplit, because it is compatible 
+% with the Matlab interpreter.

-## @deftypefn  {Function File} {[@var{cstr}] =} strsplit (@var{s}, @var{sep})
-## @deftypefnx {Function File} {[@var{cstr}] =} strsplit (@var{s}, @var{sep}, @var{strip_empty})
-## Split the string @var{s} using one or more separators @var{sep} and return
-## a cell array of strings.  Consecutive separators and separators at
-## boundaries result in empty strings, unless @var{strip_empty} is true.
-## The default value of @var{strip_empty} is false.
-##
-## 2-D character arrays are split at separators and at the original column
-## boundaries.
-##
-## Example:
-##
-## @example
-## @group
-## strsplit ("a,b,c", ",")
-##       @result{}
-##           @{
-##             [1,1] = a
-##             [1,2] = b
-##             [1,3] = c
-##           @}
-##
-## strsplit (["a,b" ; "cde"], ",")
-##       @result{}
-##           @{
-##             [1,1] = a
