build the skeleton of the xml help file associated to a Scilab function
txt = help_skeleton(funname [,path [,language]])
:funname character string : the name of the function : :path character string : the path where the file will be create if
required. If this argument is not given the skeleton is returned as a string.
: :txt the XML code or the complete XML file path :
txt = help_skeleton(funname) generates a vector of strings containing the skeleton of the XML code describing the help of the function funname.
fullpath = help_skeleton(funname,dirpath) generates the XML code describing the help of the function funname in a file named funname.xml in the directory specified by the path dirpath. In this case the function returns the file path.
function [y, z]=foo(a, b),y=a+b,z=1,endfunction
p=help_skeleton('foo',TMPDIR)
if (`isdef`_('editor') | (`funptr`_('editor')<>0)) then
`editor`_(p);
