[Oberon] Extended Oberon / Oberon-extended.

[peter at easthope.ca]

Not sure I understand the name usage correctly. 
Are "Extended Oberon" and "Oberon-extended" interchangeable?

https://github.com/andreaspirklbauer/Oberon-extended/blob/master/Documentation/Streamlining-symbol-files-in-Oberon.pdf
gives error 404.

"blob"should be "tree".  Even so 
https://github.com/andreaspirklbauer/Oberon-extended/tree/master/Documentation/Streamlining-symbol-files-in-Oberon.pdf
gives 404.  Is the Streamlining document incorporated into something else?
Moved elsewhere?

Thx,                            ... P.L.
