[Savannah-help-public] Is it okay to add code taken from other projects to my project?

[J. Scott Edwards]

Hello,

One of the things I plan to do with my (objectify) project is to
integrate it into other software, for example I am planning on
creating a version of wget integrated with my code.  Is it okay to
copy the wget source code into my project (I assume it is GPL'd)?

Another thing I have been planning to do is to integrate it with a
compiler project I worked on several years ago.  I created a compiler
from, what was then known as, SmallEiffel (the GNU Eiffel compiler).
After I made my fork they renamed it to SmartEiffel:
http://smarteiffel.loria.fr/.  I was wondering if it would be okay to
add that code to my Objectify project?  It is GPLv2.  However, I don't
believe the documentation with has a license specified.  I could leave
the documentation out if that is a problem.

Thanks for any advice.
