Path operations

[Eric Streit]

Hi,

I begin to work with the last git version of gm2.

Porting some old programs to see how it fits and runs.

I don't want to have "mixed libraries"; at first I chose Iso libs, but 
Benjamin told mo "not to use them".

So, I tried with the "Base" libraries ; I couldn't find ant "path 
manipulation" lib.

Maybe I missed it?

Can anyone help me?

Best regards

Eric

ps : maybe this lib doesn't exist, and we could make one .... the Python 
Path manipulation libs are remarquable,and we could take this for base 
working.
