Subject: [R-pkg-devel] best practices for handling a mixed-licensed package
In-Reply-To: <A29CA957-9BC0-434E-AD67-9CE557BD3C94@dcn.davis.ca.us>
This is why I recommend that if you copy an entire directory of code you
include the LICENSE file for that directory; if you copy a single file,
make the license clear at the comment in a top of the file. This is
standard practice in most open source communities.
If you?re writing open source code, I don?t think it?s necessary to retain
a lawyer in order to handle these commonplace issues. (OTOH if you?re
building a business on top of open source code, hiring a lawyer is
absolutely essential).
