Section: Operating System Functions
setpath(y)
where y is a string containing a delimited list of directories
to be searched for M files and libraries.  
The delimiter between the paths depends on the system being used.  For Win32, the
delimiter is a semicolon.  For all other systems, the delimiter is a colon.
@Example
The setpath function is straightforward.
--> getpath
ans = 
  Empty array 1 0
--> setpath('/usr/local/FreeMat/MFiles:/localhome/basu/MFiles')
--> getpath
ans = 
/usr/local/FreeMat/MFiles:/localhome/basu/MFiles
