First of all, you are repackaging Eclipse CDT and are not distributing
the source code for it; in fact, you have relicensed the entire project
with a proprietary license.  Eclipse CDT is license under EPL:


Which forbids this practice.  EPL still allows you to license your
plugin as proprietary, but you still have to release the source code of
everything else (and if you modified Eclipse CDT in some way, you also
have to release your modifications).

Secondly, what is the advantage of UltraGDB when you compare it with the
Eclipse CDT Standalone Debugger?


The Standalone Debugger is Free Software (released under the EPL as
well), and distributed along with the Eclipse CDT on some distributions
(Fedora GNU/Linux, for example).  It is nice to see people developing
other plugins and GUI's for GDB (assuming they are Free Software as
well, of course), but it looks to me that Standalone Debugger offers a
better user experience than UltraGDB.

Thank you,
