And, assuming the license is an [F]OSS one, where can I find the sources (the upstream sources as well as the Porteus build procedures, and what about Porteus-developed features)?
Kind regards, Dick

Edit: To clarify what I am looking for I changed my "... the license is an FOSS one ..." phrase into "... the license is an [F]OSS one ...".
Edit2: Again to clarify what I am looking for I changed my "... the sources" phrase into "... the sources (the upstream sources as well as the Porteus build procedures, and what about Porteus-developed features)".
